Evolution - Intelligent Design

Evolution is a process in which something passes by degrees to a different stage. (especially a more advanced or mature stage)
(biology) the sequence of events involved in the evolutionary development of a species or taxonomic group of organisms.

Previous SubjectNext Subject

Evolution is about Natural Selection and the Adaptation of Species, because those are facts that can be explained and understood by most people. Evolution does not explain where species originate from, or how life starts, that would be Physics.

Believing in God does not mean that you can't believe in evolution, and believing in evolution does not mean that you can't believe in God. Believing in God does not excuse you from knowing the facts in the same way that believing in evolution does not excuse you from knowing about religion and what it's like to believe in a God. Ignorance is the only thing that divides us. To assume that you know the origin of life is the same thing as assuming that you know who God is.

Intelligent Design

Don't confuse Life with Evolution, or confuse Evolution with Adaptation. Though they are related in certain ways, those are three different things with different definitions that are not 100 percent defined.

Traits - Heredity

Adapt is to adjust oneself to new or different conditions. Make fit for, or change to suit a new purpose.

Brain Plasticity

Adaptation is a trait with a current functional role in the life of an organism that is maintained and evolved by means of Natural Selection, which is the differential survival and reproduction of individuals over time due to differences in phenotype, which is the observable characteristics or traits, the expression of an organism's genetic code.

Adaptationism is the view that many physical and psychological traits of organisms are evolved adaptations.

Adapting to lower levels of Oxygen

Human species have adapted to lowland environment where oxygen is generally abundant. But people in Tibet, the Andes and Ethiopia have acquired the ability to survive at extremely high altitudes. While the rest of human population would suffer serious health consequences, these native inhabitants thrive well in the highest parts of the world. Tibetans has become the fastest case of human evolution in the scientific record, as it is estimated to have occurred in less than 3,000 years.

Adapting Genetically to Arsenic

Andean communities may have evolved the ability to metabolize arsenic, a trait that could be the first documented example of a toxic substance acting as an agent of natural selection in humans, Arsenic exposure can be deadly, but high in the Andes, drinking water laced with the chemical may have driven genetic adaptation in local populations. In parts of Argentina, people have been drinking poison—arsenic, to be specific—for thousands of years. The river running through the Andean village of San Antonio de los Cobres (SAC) has arsenic levels up to 80 times the safe limit established by the World Health Organization. At high doses, arsenic causes vomiting, convulsions and eventually coma. At low, chronic exposure, the metal causes skin lesions, liver damage and several types of cancers.

Scientists have found that Cephalopods are able to edit their RNA, at the expense of evolution in their genomic DNA. In other words, they are able to rapidly change on the cellular level to suit their environment, rather than relying on the slow evolution of DNA to make changes.

Differentiated is to evolve so as to lead to a new species or develop in a way most suited to the environment. Become distinct and acquire a different character. Made different (especially in the course of development) or shown to be different. Exhibiting biological specialization; adapted during development to a specific function or environment. Become different during development.

Evolution Diagram Evolution is change in the heritable characteristics of biological populations over successive generations. Evolutionary processes give rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules.

Cause and Effect
Pyramid of Complexity

Evolutionary Biology is the subfield of biology that studies the evolutionary processes that produced the diversity of life on Earth starting from a single origin of life. These processes include the descent of species, and the origin of new species.

Human Evolution is the evolutionary process that led to the emergence of anatomically modern humans.

Maturation is coming to full development; becoming mature (biology), the process of an individual organism growing organically; A purely biological unfolding of events involved in an organism changing gradually from a simple to a more complex level.

Devolution is the notion that species can revert into more "primitive" forms over time.

Coevolution occurs when changes in at least two species' genetic compositions reciprocally affect each other’s evolution.

Natural Selection is the differential survival and reproduction of individuals due to differences in phenotype.

Phenotype is the composite of an organism's observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, phenology, behavior, and products of behavior (such as a bird's nest). A phenotype results from the expression of an organism's genes as well as the influence of environmental factors and the interactions between the two. When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorph, which the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species.

Tree of Life - Biology Order

Genotype is the part (DNA sequence) of the genetic makeup of a cell, and therefore of an organism or individual, which determines a specific characteristic (phenotype) of that cell/organism/individual. Genotype is one of three factors that determine phenotype, the other two being inherited epigenetic factors, and non-inherited environmental factors.

Gene Pool is the set of all genes, or genetic information, in any population, usually of a particular species.

Taxonomy (biology) is the science of defining and naming groups of biological organisms on the basis of shared characteristics. Organisms are grouped together into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a super group of higher rank, thus creating a taxonomic hierarchy. The Swedish botanist Carl Linnaeus is regarded as the father of taxonomy, as he developed a system known as Linnaean classification for categorization of organisms and binomial nomenclature for naming organisms. With the advent of such fields of study as phylogenetics, cladistics, and systematics, the Linnaean system has progressed to a system of modern biological classification based on the evolutionary relationships between organisms, both living and extinct.

Taxon is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.

Purebred are cultivated varieties or cultivars of an animal species, achieved through the process of selective breeding. When the lineage of a purebred animal is recorded, that animal is said to be pedigreed.

Bloodline are the descendants of one individual. Ancestry of a purebred animal.

Genetic Genealogy is the use of DNA testing in combination with traditional genealogy and traditional genealogical and historical records to infer relationships between individuals. Genetic genealogy involves the use of genealogical DNA testing to determine the level and type of the genetic relationship between individuals.

Phylogenetics is the study of the evolutionary history and relationships among individuals or groups of organisms.

Genealogy also known as family history, is the study of families and the tracing of their lineages and history.

Lineage (anthropology) is a unilineal descent group that can demonstrate their common descent from a known apical ancestor. Unilineal lineages can be matrilineal or patrilineal, depending on whether they are traced through mothers or fathers, respectively. Whether matrilineal or patrilineal descent is considered most significant differs from culture to culture.
Lineage (evolution) is a series of organisms, populations, cells, or genes connected by a continuous line of descent from ancestor to descendent. Lineages are subsets of the evolutionary tree of life. Lineages are often determined by the techniques of molecular systematics.
Lineage (genetic) is a series of mutations which connect an ancestral genetic type (allele, haplotype, or haplogroup) to derivative type.
Data Lineage includes the data's origins, what happens to it and where it moves over time.

Race (biology) is an informal rank in the taxonomic hierarchy, below the level of subspecies. It has been used as a higher rank than strain, with several strains making up one race. Various definitions exist. Races may be genetically distinct phenotypic populations of interbreeding individuals within the same species, or they may be defined in other ways, e.g. geographically, or physiologically. Genetic isolation between races is not complete, but genetic differences may have accumulated that are not (yet) sufficient to separate species.

Tree of Life

Foundation Stock or foundation stock are animals that are the progenitors, or foundation, of a new breed (or crossbreed or hybrid), or of a given bloodline within such. Although usually applied to individual animals, a group of animals may be referred to collectively as foundation bloodstock when one distinct population (such a breed or a breed group) provides part of the
underlying genetic base for a new distinct population.

Convergent Evolution is the independent evolution of similar features in species of different lineages. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those group.

Exaptation describes a shift in the function of a trait during evolution. For example, a trait can evolve because it served one particular function, but subsequently it may come to serve another. Exaptations are common in both anatomy and behaviour. Bird feathers are a classic example: initially they may have evolved for temperature regulation, but later were adapted for flight. Interest in exaptation relates to both the process and products of evolution: the process that creates complex traits and the products (functions, anatomical structures, biochemicals, etc.) that may be imperfectly developed

Co-option (biology) refers to the capacity of intracellular parasites to use host-cell proteins to complete their vital cycle. Viruses use this mechanism, as their genome is small. It is also used in a different sense to refer to characters that have been exapted.

Teleology is the philosophical study of nature by attempting to describe things in terms of their apparent purpose, directive principle, or goal. A purpose that is imposed by a human use, such as that of a fork, is called extrinsic. Natural teleology, common in classical philosophy but controversial today, contends that natural entities also have intrinsic purposes, irrespective of human use or opinion. For instance, Aristotle claimed that an acorn's intrinsic telos is to become a fully grown oak tree.

Anomalistics is the use of scientific methods to evaluate anomalies (phenomena that fall outside of current understanding), with the aim of finding a rational explanation.

Evolutionary Psychology is a theoretical approach in the social and natural sciences that examines psychological structure from a modern evolutionary perspective. It seeks to identify which human psychological traits are evolved adaptations – that is, the functional products of natural selection or sexual selection in human evolution. Adaptationist thinking about physiological mechanisms, such as the heart, lungs, and immune system, is common in evolutionary biology. Some evolutionary psychologists apply the same thinking to psychology, arguing that the modularity of mind is similar to that of the body and with different modular adaptations serving different functions. Evolutionary psychologists argue that much of human behavior is the output of psychological adaptations that evolved to solve recurrent problems in human ancestral environments.

Sphenoid Bone is an unpaired bone of the neurocranium. It is situated in the middle of the skull towards the front, in front of the temporal bone and the basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended.

Regulator Gene is a gene involved in controlling the expression of one or more other genes. Regulatory sequences, which encode regulatory genes, are often 5' to the start site of transcription of the gene they regulate. In addition , these sequences can also be found 3' to the transcription start site. In both cases, whether the regulatory sequence occurs before (5') or after (3') the gene it regulates, the sequence is often many kilobases away from the transcription start site. A regulator gene may encode a protein, or it may work at the level of RNA, as in the case of genes encoding microRNAs. An example of a regulator gene is a gene that codes for a repressor protein that inhibits the activity of an operator gene (a gene which binds repressor proteins thus inhibiting the translation of RNA to protein via RNA polymerase).


Why are Mutations thought to be part of the evolutionary process?

Mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from errors during DNA replication or other types of damage to DNA, which then may undergo error-prone repair (especially microhomology-mediated end joining), or cause an error during other forms of repair, or else may cause an error during replication (translesion synthesis). Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Genetic Disorder

Mutation Rate is a measure of the rate at which various types of mutations occur over time. Mutation rates are typically given for a specific class of mutation, for instance point mutations, small or large scale insertions or deletions. The rate of substitutions can be further subdivided into a mutation spectrum which describes the influence of genetic context on the mutation rate.

Point Accepted Mutation is the replacement of a single amino acid in the primary structure of a protein with another single amino acid, which is accepted by the processes of natural selection.

Morphology (biology) is the study of the form and structure of organisms and their specific structural features.

Genes - DNA
Traits - Heredity

DNA mutation is less frequent, less than 1%, where a  SNP Mutation is more frequent.  

Synonymous Substitution is the evolutionary substitution of one base for another in an exon of a gene coding for a protein, such that the produced amino acid sequence is not modified. This is possible because the genetic code is "degenerate", meaning that some amino acids are coded for by more than one three-base-pair codon; since some of the codons for a given amino acid differ by just one base pair from others coding for the same amino acid, a mutation that replaces the "normal" base by one of the alternatives will result in incorporation of the same amino acid into the growing polypeptide chain when the gene is translated.

DNA is constantly subject to mutations, accidental changes in its code.
Mutations can lead to missing or malformed proteins, and that can lead to disease.

point mutations, frame shift mutation.
non-sense mutation, missense mutation.
conservative mutation, non-conservative mutation.

Irreducible Complexity is the argument that certain biological systems cannot evolve by successive small modifications to pre-existing functional systems through natural selection.

Genetic Variation means that biological systems – individuals and populations – are different over space. Each gene pool includes various alleles of genes. The variation occurs both within and among populations, supported by individual carriers of the variant genes. Genetic variation is brought about, fundamentally, by random mutation, which is a permanent change in the chemical structure of chromosomes. Genetic recombination also produces changes within alleles.

Genetic Drift is the change in the frequency of a gene variant (allele) in a population due to random sampling of organisms. The alleles in the offspring are a sample of those in the parents, and chance has a role in determining whether a given individual survives and reproduces. A population's allele frequency is the fraction of the copies of one gene that share a particular form. Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation.

Junctional Diversity describes the DNA sequence variations introduced by the improper joining of gene segments during the process of V(D)J recombination. This process of V(D)J recombination has vital roles for the vertebrate immune system, as it is able to generate a huge repertoire of different T-cell receptor (TCR) and immunoglobulin molecules required for pathogen antigen
recognition by T-cells and B cells, respectively. The inaccuracies of joining provided by junctional diversity is estimated to triple the diversity initially generated by these V(D)J recombinations.

Genetic Recombination is the production of offspring with combinations of traits that differ from those found in either parent. In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be passed on from the parents to the offspring. Most recombination is naturally occurring.

is the division of something into two branches or parts. "You go that way and I will go this way".
Bifurcation Theory is the mathematical study of changes in the qualitative or topological structure of a given family, such as the integral curves of a family of vector fields, and the solutions of a family of differential equations. Most commonly applied to the mathematical study of dynamical systems, a bifurcation occurs when a small smooth change made to the parameter values (the bifurcation parameters) of a system causes a sudden 'qualitative' or topological change in its behaviour.


Viruses revealed to be a major driver of human evolution. Study tracking protein adaptation over millions of years yields insights relevant to fighting today's viruses.

Tree of Life

Atavism is an evolutionary throwback, such as traits reappearing that had disappeared generations before. Atavisms can occur in several ways. One way is when genes for previously existing phenotypical features are preserved in DNA, and these become expressed through a mutation that either knocks out the overriding genes for the new traits or makes the old traits override the new one. A number of traits can vary as a result of shortening of the fetal development of a trait (neoteny) or by prolongation of the same. In such a case, a shift in the time a trait is allowed to develop before it is fixed can bring forth an ancestral phenotype.

Coccyx commonly referred to as the tailbone, is the final segment of the vertebral column in humans and apes, and certain other mammals such as horses. In animals with bony tails, it is known as tailhead or dock, in bird anatomy as tailfan. It comprises three to five separate or fused coccygeal vertebrae below the sacrum, attached to the sacrum by a fibrocartilaginous joint, the sacrococcygeal symphysis, which permits limited movement between the sacrum and the coccyx.

Human Vestigiality involves those traits (such as organs or behaviors) occurring in humans that have lost all or most of their original function through evolution. Although structures called vestigial often appear functionless, a vestigial structure may retain lesser functions or develop minor new ones. In some cases, structures once identified as vestigial simply had an unrecognized function.

Divergent Evolution is the accumulation of differences between groups, leading to the formation of new species.

Chromosome 2 (human) is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 2 is the second-largest human chromosome, spanning more than 242 million base pairs (the building material of DNA) and representing almost 8% of the total DNA in human cells.

Biological Anthropology is a scientific discipline concerned with the biological and behavioral aspects of human beings, their related non-human primates and their extinct hominin ancestors. It is a subfield of anthropology that provides a biological perspective to the systematic study of human beings.


Bilateria are animals with bilateral symmetry, i.e., they have a head ("anterior") and a tail ("posterior") as well as a back ("dorsal") and a belly ("ventral"); therefore they also have a left side and a right side. In contrast, radially symmetrical animals like jellyfish have a topside and a downside, but no identifiable front or back.

"Yes, humans are still animals, but humans have an amazing Brain, we either use it or lose it, now that's evolution."

Dollo's law of irreversibility states that evolution is not reversible.

Devolution is the notion that species can revert into more "primitive" forms over time.

Craniometry is measurement of the cranium (the main part of the skull), usually the human cranium. It is a subset of cephalometry, measurement of the head, which in humans is a subset of anthropometry, measurement of the human body. It is distinct from phrenology, the pseudoscience that tried to link personality and character to head shape, and physiognomy, which tried the same for facial features. However, these fields have all claimed the ability to predict traits or intelligence.

2 million years ago, early humans were established and had split into at least two species:
Homo Habilis is a species of the tribe Hominini, during the Gelasian and early Calabrian stages of the Pleistocene period, which lived between roughly 2.1 and 1.5 million years ago.
Homo Rudolfensis is an extinct species of the Hominini tribe known only through a handful of representative fossils, the first of which was discovered by Bernard Ngeneo, a member of a team led by anthropologist Richard Leakey and zoologist Meave Leakey in 1972, at Koobi Fora on the east side of Lake Rudolf (now Lake Turkana) in Kenya.

Isochron Burial Dating uses Radioisotopes oldest hominid skeletons ever dated at 3.67 million years old.
Radionuclide is an atom that has excess nuclear energy, making it unstable. 

Chimpanzee Human last Common Ancestor is the last common ancestor shared by the extant Homo (human) and Pan (chimpanzee) genera of Hominini. 

Humans have 46 chromosomes, 2 less then the common potato.


Hominidae are known as great apes or hominids, are a taxonomic family of primates that includes seven extant species in four genera: Pongo, the Bornean and Sumatran orangutan; Gorilla, the eastern and western gorilla; Pan, the common chimpanzee and the bonobo; and Homo, the human and near-human ancestors and relatives (e.g., the Neanderthal).

Bonobo is an endangered great ape and one of the two species making up the genus Pan; the other is Pan troglodytes, or the common chimpanzee.

Homo Sapiens (5.5 million) is the binomial nomenclature (also known as the scientific name) for the only extant human species.

Homo Erectus (200,000) meaning "upright man", from the Latin ērigere, "to put up, set upright") is still in existence species of hominid that lived throughout most of the Pleistocene geological epoch.

Human are the only extant members of Hominina clade (or human clade), a branch of the taxonomical tribe Hominini belonging to the family of great apes.

Homology is the existence of shared ancestry between a pair of structures, or genes, in different taxa.

Genetic Genealogy is the use of DNA testing in combination with traditional genealogy and traditional genealogical and historical records to infer relationships between individuals.

Primate arose from ancestors that lived in the trees of tropical forests; many primate characteristics represent adaptations to life in this challenging three-dimensional environment. Most primate species remain at least partly arboreal.

Mammal distinguished from reptiles and birds by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands. Mammals include the largest animals on the planet, the great whales, as well as some of the most intelligent, such as elephants, primates and cetaceans.

Neanderthals are the closest relatives in the Homo genus, they thrived for hundreds of thousands of years, only to die out about 40,000 years ago. "The theory is that no one wanted to marry a Neanderthal, so they went extinct."

How did Brains Evolve?

Encephalization is defined as the amount of brain mass related to an animal's total body mass.

Recapitulation Theory is a largely discredited biological hypothesis that the development of the embryo of an animal, from fertilization to gestation or hatching (ontogeny), goes through stages resembling or representing successive stages in the evolution of the animal's remote ancestors (phylogeny).

Devolution is what our current education system is doing.

“Change is not merely necessary to life - it is life.”  Alvin Toffler

"Knowing what you're made out of does not explain how you were made....Knowing E=mc2 does not fully explain what energy is, or does it explain what matter is, or what light is. So what do we know?"

Yes we know animals evolve or adapt because we have evidence. But you can’t prove that new species evolve from other species. Why would a lizard want to evolve into a horse? And why didn't Dinosaurs eventually grow brains within 160 million years? Yes those are stupid questions, but that's where it all starts. 

Cope's Rule postulates that population lineages tend to increase in body size over evolutionary time.

When something doesn't make sense it means you don't have all the information, so what's missing? Just because animals share the same Genes does not mean that one animal evolved from the other animal, it simply means that they share the same building blocks of Life. So what causes these little variations, like the variations we see in humans? Is it a combination of a Variable and a Fractal? Is evolution part Physics?

Evolution has a hard time proving Diversity or Variety.

Cambrian Explosion was the relatively short evolutionary event, beginning around 541 million years ago in the Cambrian period, during which most major animal phyla appeared, as indicated by the fossil record. Lasting for about the next 20–25 million years, it resulted in the divergence of most modern metazoan phyla. Additionally, the event was accompanied by major diversification of other organisms. Prior to the Cambrian explosion, most organisms were simple, composed of individual cells occasionally organized into colonies. Over the following 70 to 80 million years, the rate of diversification accelerated by an order of magnitude and the diversity of life began to resemble that of today. Almost all the present phyla appeared during this period, with the exception of Bryozoa, which made its earliest known appearance later, in the Lower Ordovician. The Cambrian marked a profound change in life on Earth; prior to the Cambrian, the majority of living organisms on the whole were small, unicellular and simple; the Precambrian Charnia being exceptional. Complex, multicellular organisms gradually became more common in the millions of years immediately preceding the Cambrian, but it was not until this period that mineralized—hence readily fossilized—organisms became common. The rapid diversification of lifeforms in the Cambrian, known as the Cambrian explosion, produced the first representatives of all modern animal phyla. Phylogenetic analysis has supported the view that during the Cambrian radiation, metazoa (animals) evolved monophyletically from a single common ancestor: flagellated colonial protists similar to modern choanoflagellates. Although diverse life forms prospered in the oceans, the land was comparatively barren—with nothing more complex than a microbial soil crust and a few molluscs that emerged to browse on the microbial biofilm. Most of the continents were probably dry and rocky due to a lack of vegetation. Shallow seas flanked the margins of several continents created during the breakup of the supercontinent Pannotia. The seas were relatively warm, and polar ice was absent for much of the period.

Why do we have some species staying the same for millions of years while other species in the same time period evolving or Adapting?

Something's just seem to appear out of no where, so where did they originate from? And somehow, even through Mass Extinctions, life still found a way to survive in some form. And after each Mass Extinction, life never returns in the same way that it was before. So it doesn't look like a normal process of life, it kind of looks like someone or something is trying something new, like some form of Intelligence trying to define itself. There are huge gaps of missing information. Both religious and non-religious people love to fill those gaps with their beliefs. But if I had a choice of filling the gap of missing information with something, I would rather say that it was God then to say that it was nothing. Not that I would, but I do understand why some people would say that. I mean, who would want to be considered just a freak of nature. I'm either a lucky piece of shit or I'm here for a reason, I would like to believe that I'm here for a reason. If a belief stops you from learning, then it's not a good belief to hold. Being biased against new knowledge and new information leaves you vulnerable and reduces your ability to adapt and to make good decisions. I know that there is no guarantee of survival, but reducing my odds to live makes no sense at all.

I like to believe that Human Ascended instead of Descended. Our ancestors where the building blocks of life, not the origin of life.

Last Universal Ancestor (LUA), also called the last universal common ancestor (LUCA), cenancestor, or progenote, is the most recent organism from which all organisms now living on Earth have a common descent. Thus, it is the most recent common ancestor (MRCA) of all current life on Earth. As such, it should not be assumed to be the first living organism. The LUA is estimated to have lived some 3.5 to 3.8 billion years ago (sometime in the Paleoarchean era). The earliest evidence for life on Earth is biogenic graphite found in 3.7 billion-year-old metamorphized sedimentary rocks discovered in Western Greenland and microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. A study in 2015 found potentially biogenic carbon from 4.1 billion years ago in ancient rocks in Western Australia. Such findings would indicate the existence of different conditions on Earth during that period than what is generally assumed today and point to an earlier origination of life. In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor (LUCA) of all life living on Earth.

Most Recent Common Ancestor (MRCA) of any set of organisms is the most recent individual from which all organisms in a group, for example a haplogroup, are directly descended. The term is often applied to human genealogy.

Just because you can’t explain something now, doesn’t mean that you never will. Believing you know the answer is different from actually knowing the answer. Plus we only have one planet that we know of where life exists. So from a science point of view, having only one example of life can never be hard evidence, and that this is just the normal process of life. To me this is a silly argument and I take no sides in this discussion. Both sides have good claims, good points and good theories. Even though this is a healthy discussion that needs more looking into, I can’t help to know that we have more important and more urgent problems that need to be addressed. This is a distraction, but we will come back to this, just not now.

Beck - Loser (youtube)

"Adaptation can be dangerous, especially when you become adapted to something that is slowly killing you. Adaptation only buys you some time, it does not guarantee you survival. Only humans have the ability to over come this vulnerability, that's why we are here. So we can't f*ck this up, if we do, we're dead, like all other animal species before us. I don't want to become bacteria again, that would suck, it's not the life that I want, or want for anyone else."

Maybe evolution is just another form of consciousness, or some form of intelligence that we are unable to comprehend. Maybe evolution is Gods work? Who else could have figured out that the only way you can have a sustaining planet is to give plants and animals the ability to evolve, adapt and to flourish. If you don’t adapt you die. And that is exactly where humans are today. Evolution has given all of us some extremely valuable information that Cause and Effect is real and that Cause and Effect should not be ignored. Everyone should just stick with the facts. Evolution does not explain everything and Religion does not explain everything, so why are we so threatened by someone else's beliefs? As long as no one ever stops asking questions, no one should ever fear or feel threatened by other peoples beliefs. The most important thing is that we keep sharing information and keep documenting our world. You should never claim that you have all the answers. If you are stubborn and selfish with your beliefs then the message you are trying to convey will only distort information and confuse people into believing that there are no more questions to ask. And that is simply a crime against humanity. A good documentary to watch is War on Science. People are overreacting in this film but I understand their passion. Another example of people overreacting is in a film called “The Shape of Life” from PBS. This film has great information but it's kind of ruined because they pretend to know the answers of evolution. These are the kinds of things we need to stop doing if we are going to educate people and secure our species survival. A better film to watch is Miracle Planet. To me it seems that a single cell is intelligent life. How and why? I don't know.

Humans are 90% bacteria. So I guess if you want to survive on a planet you better find a way to have a symbiotic relationship with a planets natural life forms, life forms that have lived and survived on this planet for billions of years. I guess that is how we will survive on another planet, by finding out what has lived and survived there the longest, and then learn how to have a symbiotic relationship with those organisms.

So what's wrong with saying "I don't know?

"Teaching evolution is not bad, what's bad is how you teach evolution and how it's understood by people. The same thing with religion, teaching religion is not bad, it's how you teach Religion and how it's understood." If evolution is information evolving, and if God is information, then I guess you're both right.

This is just another Human Transition, maybe evolution and intelligent design are the same thing?....Can I go now?

"You can't prove that God does not exist, or can you prove that God does exist. We should stick with the things that we can prove and save the things that we cannot prove for later time. Because if we don't solve our greatest problems, that we all face, we will never live to see God, or live to see if there isn't a God."

It is difficult to understand how anyone can believe that the Nervous System, particularly the brain, could have been produced by evolutionary randomness and selection. We have barely touched on some of the electrical design present in the rest of the body. The truth is that scientists are always discovering more about its workings, since its complexity, which far surpasses anything produced by man, is nothing short of a miracle. Truly we can say with David, “I will praise You, for I am fearfully and wonderfully made; Your works are marvelous and my soul knows it very well”  (Psalm 139:14). (Craig Savige)

Modern Humans

"Whether you believe that evolution or God designed our brain doesn't really matter, what matters is that you never ignore the human brains enormous potential, and its weaknesses. The knowledge that we have acquired about the human brain is invaluable. So knowing who or what made it will not be as important as learning how the brain works and learning how effectively we can use its power. So when we finally do figure out who or what made us, it will not come to us as some big surprise, because after all, we have brains."

"Thank God my brain is smarter then I am."

"God has reasons for doing things, and evolution has reasons too, and if God created evolution, then evolution can't be wrong."

"I couldn't even imagine being anything else but human. Human to me is the greatest way to experience life. And when we imagine what other life from other planets looks like, that makes me even prouder, because the human form to me is the most enjoyable machine a person could ever design. I couldn't even dream of a better human. Some people would say a human with wings, or a human with superman powers. But we already have those because of the machines that we will built."

If you didn't have what you needed to know what you were missing, then how would you evolve into it? I know information is some form of intelligence, what I don't know is how did information see when it didn't have what was needed to see what it didn't have?

I think that humans take for granted that our way of seeing through the eyes is the only form of sight.

"I'm the evolutionary result of a seed that was born thousands of years ago, and yet it feels like the first time being alive."

Some people believe that 10 million years ago that some of the monkeys changed their diet just enough to evolve into humans. Though I fully understand the importance of nutrition and how diet can improve appearance and health, I'm having a little trouble understanding just what nutritional substances can cause a species body to change and grow a better brain? I'm positive we can repeat this theory. We just need to start feeding monkeys better food and lets see what happens. Of course it will take many life times to see the results, but we should start seeing some changes, maybe Planet of the Apes?

Humanzee is a hypothetical chimpanzee/human hybrid. An unsuccessful attempt to breed such a hybrid was made by Ilya Ivanovich Ivanov in the 1920s. There have been occasional reports of human-chimpanzee hybridization, notably regarding a performing chimp named Oliver during the 1970s, but none of them have been confirmed. There has been what people think to be a sighting of a humanzee in July of 2012 in Colorado. Similarly, the possibility of a chimpanzee–gorilla hybrid, known as koolakamba, also remains unsubstantiated. Devolution

We know the about the negative effects from a poor nutritional diet and isolation, children are smaller and less developed, just like early man. Does that mean that only a man can grow into man. Humans evolved from humans? This is like finding out that your father is not your real father. Welcome to the party.

And since we have evidence and experience in knowing that some Miracles can actually be explained, we still have to keep trying to understand our world. We have enough evidence to prove that our increased understanding of the world has benefited us in many ways. Not to say that it was Perfect, But at least we are definitely more aware of our possibilities and of our human potential.

"It's not the strongest of species that survives, nor the most intelligent, but the one most adaptable to change."

Charles Darwin was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. He believed that all species of life have descended over time from common ancestors. (12 February 1809 – 19 April 1882). Charles wrote the 1859 book the Origin of Species, which introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.

People didn't have enough information and knowledge years ago that was needed in order to explain complex ideas and concepts. But now we do, and we can be more precise. Not that we can fully explain all knowledge correctly to all people, but at least we know now that the acquisition of more knowledge is always needed to further our understanding and also to help to explain knowledge so that more people can understand. The mistake that most people make is that they believed that all knowledge is known, so they make assumptions instead of realizing that more knowledge, information and research is needed. So not only do we have more knowledge and information today, we also have the intelligence to know that more knowledge and information is always needed. So we can now make less assumptions, make less mistakes, and we never assume that we know everything, thus we keep learning.

"I wouldn't want to assume that life started on this planet. I'm just saying that life had to start somewhere. Where and how, I don't know? But I hope we find out, because that would be an incredible story. We know that our galaxy was not the first galaxy born in our universe. So we may have brothers and sisters, some we may never know? But my guess is, that we will find our siblings, because everything usually leaves some kind of a trace."

Trace is a just detectable amount. An indication that something has been present. A visible mark (as a footprint) left by the passage of person or animal or vehicle. Discover traces of. Follow, discover, or ascertain the course of development of something. To go back over again. Pursue or chase relentlessly.

Detect is to discover or determine the existence, presence, or fact of.

Indication is a datum about some physical state that is presented to a user by a meter or similar instrument.

Intelligent Design

Intelligent Design is the view that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection. "Things just happened Dude" or "This looks to amazing to be just some natural sequence of events, first you need to define what natural is, which you can't because this is everyone's first time here, thus, we have nothing to compare life to, nothing."...so we need to start over, this time everyone needs to have an open mind. Are we just Iterations in the process of Development?

Biogenesis is the production of new living organisms or organelles. The hypothesis of biogenesis, attributed to Louis Pasteur, states that complex living things come only from other living things, by reproduction (e.g. a spider lays eggs, which develop into spiders). That is, modern life does not arise from non-living material, which was the position held by spontaneous generation.

Extra Terrestrial Life (space)

Terraforming is the process of deliberately modifying a planets atmosphere, temperature, surface topography or ecology to be similar to the environment of Earth to make it habitable by Earth-like life.

Exogenesis or
Panspermia, is the hypothesis that Life exists throughout the Universe, distributed by meteoroids, asteroids, comets, planetoids, and also by spacecraft in the form of unintended contamination by microorganisms. Panspermia is a hypothesis proposing that microscopic life forms that can survive the effects of space, such as extremophiles, become trapped in debris that is ejected into space after collisions between planets and small Solar System bodies that harbor life. Some organisms may travel dormant for an extended amount of time before colliding randomly with other planets or intermingling with protoplanetary disks. If met with ideal conditions on a new planet's surfaces, the organisms become active and the process of evolution begins. Panspermia is not meant to address how life began, just the method that may cause its distribution in the Universe.

Knowledge Preservation

Astrobiology is the study of the origin, evolution, distribution, and future of Life in the universe: extraterrestrial life and life on Earth. Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does (the term exobiology is similar but more specific—it covers the search for life beyond Earth, and the effects of extraterrestrial environments on living things.

Anthropic Principle is the philosophical consideration that observations of the Universe must be compatible with the conscious and sapient life that observes it. Some proponents of the anthropic principle reason that it explains why this universe has the age and the fundamental physical constants necessary to accommodate conscious life. As a result, they believe it is unremarkable that this universe has fundamental constants that happen to fall within the narrow range thought to be compatible with life.

Cellular Automaton is a discrete model studied in computability theory, mathematics, physics, complexity science, theoretical biology and microstructure modeling. A cellular automaton consists of a regular grid of cells, each in one of a finite number of states, such as on and off (in contrast to a coupled map lattice). The grid can be in any finite number of dimensions. For each cell, a set of cells called its neighborhood is defined relative to the specified cell. An initial state (time t = 0) is selected by assigning a state for each cell. A new generation is created (advancing t by 1), according to some fixed rule (generally, a mathematical function) that determines the new state of each cell in terms of the current state of the cell and the states of the cells in its neighborhood. Typically, the rule for updating the state of cells is the same for each cell and does not change over time, and is applied to the whole grid simultaneously, though exceptions are known, such as the stochastic cellular automaton and asynchronous cellular automaton.

Conway's Game of Life is a cellular automaton devised by the British mathematician John Horton Conway in 1970. The "game" is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an initial configuration and observing how it evolves, or, for advanced "players", by creating patterns with particular properties. The universe of the Game of Life is an infinite two-dimensional orthogonal grid of square cells, each of which is in one of two possible states, alive or dead, or "populated" or "unpopulated". Every cell interacts with its eight neighbours, which are the cells that are horizontally, vertically, or diagonally adjacent. At each step in time, the following transitions occur: Any live cell with fewer than two live neighbours dies, as if caused by underpopulation. Any live cell with two or three live neighbours lives on to the next generation. Any live cell with more than three live neighbours dies, as if by overpopulation. Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction. The initial pattern constitutes the seed of the system. The first generation is created by applying the above rules simultaneously to every cell in the seed—births and deaths occur simultaneously, and the discrete moment at which this happens is sometimes called a tick (in other words, each generation is a pure function of the preceding one). The rules continue to be applied repeatedly to create further generations.

Zero-Player Game is a game that has no sentient players. In computer games, the term refers to programs that use artificial intelligence rather than human players.

Creationism is the religious belief that the universe and Life originated "from specific acts of divine creation," as opposed to the scientific reasons that they came about through natural processes.

Abiogenesis or informally, the origin of life, is the natural process by which life arises from non-living matter, such as simple organic compounds. It is thought to have occurred on Earth between 3.8 and 4.1 billion years ago. Abiogenesis is studied through a combination of laboratory experiments and extrapolation from the characteristics of modern organisms, and aims to determine how pre-life chemical reactions gave rise to life on Earth.

Spontaneous Generation is an obsolete body of thought on the ordinary formation of living organisms without descent from similar organisms. Typically, the idea was that certain forms such as fleas could arise from inanimate matter such as dust, or that maggots could arise from dead flesh. A variant idea was that of equivocal generation, in which species such as tapeworms arose from unrelated living organisms, now understood to be their hosts. Doctrines supporting such processes of generation held that these processes are commonplace and regular. Such ideas are in contradiction to that of univocal generation: effectively exclusive reproduction from genetically related parent(s), generally of the same species.

Lazarus Taxon is a taxon that disappears for one or more periods from the fossil record, only to appear again later. Likewise in conservation biology and ecology, it can refer to species or populations that were thought to be extinct, and are rediscovered. The term refers to the story in the Christian biblical Gospel of John, in which Jesus Christ raised Lazarus from the dead.


Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. The extreme opposite of endemism is cosmopolitan distribution. An alternative term for a species that is endemic is precinctive, which applies to species (and subspecific categories) that are restricted to a defined geographical area.

Life is not a process of evolution, evolution is a process of life. First comes life then comes evolution. Evolution does not create life. Life creates evolution. How did life get here? Is there another dimension or invisible landscape that allows life to travel any where in the universe? Life may sense where life can exist, so life goes to that planet and adapts to the environment of that planet, so that life can evolve and develop using the chemical building blocks that are available. There can only be life where life has existed before. What came first the chicken or the egg? Of course we may never know where life truly originated from. Life certainly did not originate from this planet. Our planet was not the first planet or will it be the last planet to support life.

Convergent Evolution is the independent evolution of similar features in species of different lineages. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups.

Divergent Evolution is the accumulation of differences between groups, leading to the formation of new species.

Iteration - Development

The Universe is not perfect or finely tuned. Chaos by Design or Meaningful Coincidences? The Universe does have consistencies, stabilities and order, most likely by design, why else? But nothing lasts forever. Though Atoms do last for an extremely long time that seems to be forever, (10^35 years). Planets and stars do have limited life spans on the average of around 10 billion years, which seems to be plenty of time to enjoy Life, and also, plenty of time to find a new home when that time comes. The Universe looks like someone had an idea about how they wanted to create a universe, and then experimented and learned along the way to find out which processes work the best. Earth seems to be the only successful result that we know of from all those different experiments that the universe is still currently experimenting with. The Universe is chaotic, stars exploding, planets dying, radiation, and asteroids destroying planets causing mass extinctions. Then on earth you have diseases, wars, crimes and lots of natural disasters. You can't say that all those horrible things that happen to people are by design or from God. Know one in their right mind would design a world like that. But maybe all these things that kill life are all part of the process of learning and trying to figure out how to make life flourish. Life and the Universe looks like one big experiment. Life is trying to figure out what works best. So of course we still have some work to do, and so does God. And I would rather help God succeed then work against God. I really think that God is on to something. Intelligent design is work in progress. So this is more about persistence. And Persistence is something that humans are born with. Look at any child and you can see the human spirit is alive and well. Life is a work in progress, it's not all by design or from evolution, but by will. And we will survive.

I Will Survive - Gloria Gaynor (1978) This song is about how she longer needs ignorance in her life. So the man she sings about represents ignorance.

Cell Biology is the basic structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life that can replicate independently, and cells are often called the "building blocks of life". The study of cells is called cell biology. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. Organisms can be classified as unicellular (consisting of a single cell; including bacteria) or multicellular (including plants and animals). While the number of cells in plants and animals varies from species to species, humans contain more than 10 trillion (1012) cells. Most plant and animal cells are visible only under a microscope, with dimensions between 1 and 100 micrometres.

Mitochondrion is a double membrane-bound organelle found in all eukaryotic organisms. Some cells in some multicellular organisms may however lack them (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures. To date, only one eukaryote, Monocercomonoides, is known to have completely lost its mitochondria. The word mitochondrion comes from the Greek μίτος, mitos, "thread", and χονδρίον, chondrion, "granule" or "grain-like". Mitochondria generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy. Mitochondria are commonly between 0.75 and 3 μm in diameter but vary considerably in size and structure. Unless specifically stained, they are not visible. In addition to supplying cellular energy, mitochondria are involved in other tasks, such as signaling, cellular differentiation, and cell death, as well as maintaining control of the cell cycle and cell growth. Mitochondrial biogenesis is in turn temporally coordinated with these cellular processes. Mitochondria have been implicated in several human diseases, including mitochondrial disorders, cardiac dysfunction, heart failure and autism. The number of mitochondria in a cell can vary widely by organism, tissue, and cell type. For instance, red blood cells have no mitochondria, whereas liver cells can have more than 2000; The organelle is composed of compartments that carry out specialized functions. These compartments or regions include the outer membrane, the intermembrane space, the inner membrane, and the cristae and matrix. Although most of a cell's DNA is contained in the cell nucleus, the mitochondrion has its own independent genome that shows substantial similarity to bacterial genomes. Mitochondrial proteins (proteins transcribed from mitochondrial DNA) vary depending on the tissue and the species. In humans, 615 distinct types of protein have been identified from cardiac mitochondria, whereas in rats, 940 proteins have been reported. The mitochondrial proteome is thought to be dynamically regulated.

Ribosome is a complex molecular machine, found within all living cells, that serves as the site of biological protein production. Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules. Ribosomes consist of two major components: the small ribosomal subunit, which reads the RNA, and the large subunit, which joins amino acids to form a polypeptide chain. Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins. The ribosomes and associated molecules are also known as the translational apparatus. Ribosome is a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and Protein.

Hydrocarbon is an organic compound consisting entirely of hydrogen and carbon, and thus are group 14 hydrides. Hydrocarbons from which one hydrogen atom has been removed are functional groups, called hydrocarbyls. Aromatic hydrocarbons (arenes), alkanes, alkenes, cycloalkanes and alkyne-based compounds are different types of hydrocarbons.
Polycyclic Aromatic Hydrocarbon are hydrocarbons—organic compounds containing only carbon and hydrogen—that are composed of multiple aromatic rings (organic rings in which the electrons are delocalized).

Lipids comprise a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.


Amino Acids are biologically important organic compounds containing amine (-NH2) and carboxyl (-COOH) functional groups, along with a side-chain (R group) specific to each amino acid. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, though other elements are found in the side-chains of certain amino acids. About 500 amino acids are known (though only 20 appear in the genetic code) and can be classified in many ways.

Cellulose is an organic compound, a polysaccharide consisting of a linear chain of several hundred to many thousands of β(1→4) linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is 90%, that of wood is 40–50% and that of dried hemp is approximately 57%.

Cell Death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, or may result from such factors as disease, localized injury, or the death of the organism of which the cells are part.


Programmed Cell Death is cell death mediated by an intracellular program. PCD is carried out in a regulated process, which usually confers advantage during an organism's life-cycle. For example, the differentiation of fingers and toes in a developing human embryo occurs because cells between the fingers apoptose; the result is that the digits are separate. PCD serves fundamental functions during both plant and metazoa (multicellular animals) tissue development.

Apoptosis is a process of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes (morphology) and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, chromosomal DNA fragmentation, and global mRNA decay. Between 50 and 70 billion cells die each day due to apoptosis in the average human adult.[a] For an average child between the ages of 8 and 14, approximately 20 billion to 30 billion cells die a day.

Brain Cells

Mitotic Catastrophe refers to a mechanism of delayed mitotic-linked cell death, a sequence of events resulting from premature or inappropriate entry of cells into mitosis that can be caused by chemical or physical stresses.

Cytostasis is the inhibition of cell growth and multiplication. Cytostatic refers to a cellular component or medicine that inhibits cell growth. Cytostasis is an important prerequisite for structured multicellular organisms. Without regulation of cell growth and division only unorganized heaps of cells would be possible. Chemotherapy of cancer, treatment of skin diseases and treatment of infections are common use cases of cytostatic drugs. Active hygienic products generally contain cytostatic substances. Cytostatic mechanisms and drugs generally occur together with cytotoxic ones.

Cellular Respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy in the process, as weak so-called "high-energy" bonds are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. Cellular respiration is considered an exothermic redox reaction which releases heat. The overall reaction occurs in a series of biochemical steps, most of which are redox reactions themselves. Although technically, cellular respiration is a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow release of energy from the series of reactions. Nutrients that are commonly used by animal and plant cells in respiration include
sugar, amino acids and fatty acids, and the most common oxidizing agent (electron acceptor) is molecular oxygen (O2). The chemical energy stored in ATP (its third phosphate group is weakly bonded to the rest of the molecule and is cheaply broken
allowing stronger bonds to form, thereby transferring energy for use by the cell) can then be used to drive processes requiring energy, including biosynthesis, locomotion or transportation of molecules across cell membranes.

Cell Damage can occur as a result of an adverse stimulus which disrupts the normal homeostasis of affected cells. Among other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors. Cell damage can be reversible or irreversible. Depending on the extent of injury, the cellular response may be adaptive and where possible, homeostasis is restored. Cell death occurs when the severity of the injury exceeds the cell’s ability to repair itself. Cell death is relative to both the length of exposure to a harmful stimulus and the severity of the damage caused. Cell death may occur by necrosis or apoptosis.

DNA Repair

Cellular Waste Product are formed as a by-product of cellular respiration, a series of processes and reactions that generate energy for the cell, in the form of ATP. Two examples of cellular respiration creating cellular waste products are aerobic respiration and anaerobic respiration.

Necrosis is a form of cell injury which results in the premature death of cells in living tissue by Autolysis, which is known as self-digestion, refers to the destruction of a cell through the action of its own enzymes. It may also refer to the digestion of an enzyme by another molecule of the same enzyme.

Cell Cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.

Chimera is a single organism composed of cells from different zygotes. This can result in male and female organs, two blood types, or subtle variations in form.

Cell Division is the process by which a parent cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis). Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions: homologous chromosomes are separated in the first division, and sister chromatids are separated in the second division. Both of these cell division cycles are used in sexually reproducing organisms at some point in their life cycle, and both are believed to be present in the last eukaryotic common ancestor. Prokaryotes also undergo a vegetative cell division known as binary fission, where their genetic material is segregated equally into two daughter cells. All cell divisions, regardless of organism, are preceded by a single round of DNA Replication.

Cell Potency is a cell's ability to differentiate into other cell types. The more cell types a cell can differentiate into, the greater its potency. Potency is also described as the gene activation potential within a cell which like a continuum begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency and finally unipotency. Potency is taken from the Latin term "potens" which means "having power".

Zygote is a eukaryotic cell formed by a fertilization event between two gametes.

Scientists turn skin cells into heart cells and brain cells using drugs. Studies represent first purely chemical cellular reprogramming, changing a cell's identity without adding external genes.

Blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass (ICM) which subsequently forms the embryo. The outer layer of the blastocyst consists of cells collectively called the trophoblast. This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoele. The trophoblast gives rise to the placenta.

Labile Cell are cells that multiply constantly throughout life. The cells are alive for only a short period of time. Due to this, they can end up reproducing new Stem Cells and replace functional cells. Especially if the cells become injured through a process called necrosis, or even if the cells go through apoptosis. The way these cells regenerate and replace themselves is quite unique. While going through cell division, one of the two daughter cells actually becomes a new stem cell. This occurs so then that daughter cell can end up restoring the population of the stem cells that were lost. The other daughter cell separates itself into a functional cell in order to replace the lost, or injured cells during this process. Labile cells are one type of the cells that are involved in the division of cells. The other two types that are involved include stable cells and permanent cells. Each of these type of cells respond to injuries of the cells they occupy differently. Hepatocytes of the liver are thought to be a form of a labile cell because they can regenerate after they become injured. An example of this kind of regeneration can consist of performing a pediatric liver transplant. In which it consists of taking a piece of an adult's liver to replace a child's whole liver. Then the adult liver that was transplanted for the child's, would regenerate very quickly to around a normal size liver. Other cell types that are thought to be cells that are constantly dividing include skin cells, cells in the gastrointestinal tract, and blood cells in the bone marrow. Acting as stem cells for these cell types. In labile cells, it is not a speed-up in the segments of the cell cycle (i.e. G1 phase, S phase, G2 phase and M phase), but rather a short or absent G0 phase that is responsible for the cells' constant division.

Stable Cell are cells that multiply only when needed. They spend most of the time in the quiescent G0 phase of the cell cycle, but can be stimulated to enter the cell cycle when needed. Examples include: the liver, the proximal tubules of the kidney, and endocrine glands.

Permanent Cell are cells that are incapable of regeneration. These cells are considered to be terminally differentiated and non proliferative in postnatal life. This includes brain cells, neurons, heart cells, skeletal muscle cells and RBCs.

Fission (biology) is the division of a single entity into two or more parts and the regeneration of those parts into separate entities resembling the original. The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts. The fission may be binary fission, in which a single entity produces two parts, or multiple fission, in which a single entity produces multiple parts.

Metabolic Pathways Diagram Metabolic Network is the complete set of metabolic and physical processes that determine the physiological and biochemical properties of a cell. As such, these networks comprise the chemical reactions of metabolism, the metabolic pathways, as well as the regulatory interactions that guide these reactions. With the sequencing of complete genomes, it is now possible to reconstruct the network of biochemical reactions in many organisms, from bacteria to human.

Metabolic Network Modelling allows for an in-depth insight into the molecular mechanisms of a particular organism. In particular, these models correlate the genome with molecular physiology. A reconstruction breaks down metabolic pathways (such as glycolysis and the Citric acid cycle) into their respective reactions and enzymes, and analyzes them within the perspective of the entire network. In simplified terms, a reconstruction collects all of the relevant metabolic information of an organism and compiles it in a mathematical model. Validation and analysis of reconstructions can allow identification of key features of metabolism such as growth yield, resource distribution, network robustness, and gene essentiality. This knowledge can then be applied to create novel biotechnology. In general, the process to build a reconstruction is as follows: Draft a reconstruction. Refine the model. Convert model into a mathematical/computational representation. Evaluate and debug model through experimentation.

Cytoplasm is the material or protoplasm within a living cell, excluding the cell nucleus. It comprises cytosol (the gel-like substance enclosed within the cell membrane) and the organelles – the cell's internal sub-structures. All of the contents of the cells of prokaryote organisms (such as bacteria, which lack a cell nucleus) are contained within the cytoplasm. Within the cells of eukaryote organisms the contents of the cell nucleus are separated from the cytoplasm, and are then called the nucleoplasm. The cytoplasm is about 80% water and usually colorless.

Microtubule are a component of the cytoskeleton, found throughout the cytoplasm.

Cytoskeleton is present in all cells of all domains of life (archaea, bacteria, eukaryotes). It is a complex network of interlinking filaments and tubules that extend throughout the cytoplasm, from the nucleus to the plasma membrane. The cytoskeletal systems of different organisms are composed of similar proteins. In eukaryotes, the cytoskeletal matrix is a dynamic structure composed of three main proteins, which are capable of rapid growth or disassembly dependent on the cell's requirements at a certain period of time.

Stem Cells

Stem Cell are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. They are found in multicellular organisms. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In a developing embryo, stem cells can differentiate into all the specialized cells—ectoderm, endoderm and mesoderm (see induced pluripotent stem cells)—but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues. There are three known accessible sources of autologous adult stem cells in humans: Bone marrow, which requires extraction by harvesting, that is, drilling into bone (typically the femur or iliac crest). Adipose tissue (lipid cells), which requires extraction by liposuction. Blood, which requires extraction through apheresis, wherein blood is drawn from the donor (similar to a blood donation), and passed through a machine that extracts the stem cells and returns other portions of the blood to the donor. Stem cells can also be taken from umbilical cord blood just after birth. Of all stem cell types, autologous harvesting involves the least risk. By definition, autologous cells are obtained from one's own body, just as one may bank his or her own blood for elective surgical procedures. Adult stem cells are frequently used in various medical therapies (e.g., bone marrow transplantation). Stem cells can now be artificially grown and transformed (differentiated) into specialized cell types with characteristics consistent with cells of various tissues such as muscles or nerves. Embryonic cell lines and autologous embryonic stem cells generated through somatic cell nuclear transfer or dedifferentiation have also been proposed as promising candidates for future therapies.

Adult Stem Cell are undifferentiated cells, found throughout the body after development, that multiply by cell division to replenish dying cells and regenerate damaged tissues. More accurately known as somatic stem cells (from Greek Σωματικóς, meaning of the body), because they are usually more plentiful in juvenile (child) than in adult animal and human bodies

Induced Pluripotent Stem Cell are a type of pluripotent stem cell that can be generated directly from adult cells.

Embryonic Stem Cell are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage preimplantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells. Isolating the embryoblast or inner cell mass (ICM) results in destruction of the blastocyst, which raises ethical issues, including whether or not embryos at the pre-implantation stage should be considered to have the same moral or legal status as more developed human beings.

Mesenchymal Stem Cell are multipotent stromal cells that can differentiate into a variety of cell types, including: osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells). This phenomenon has been documented in specific cells and tissues in living animals and their counterparts growing in tissue culture.

Adipose-derived Mesenchymal

Mesenchyme is a type of tissue characterized by loosely associated cells that lack polarity and are surrounded by a large extracellular matrix.

Stromal Cell are connective tissue cells of any organ, for example in the uterine mucosa (endometrium), prostate, bone marrow, lymph node and the ovary. They are cells that support the function of the parenchymal cells of that organ. Fibroblasts and pericytes are among the most common types of stromal cells.

Beta Cell are a type of cell found in the pancreatic islets of the pancreas. They make up 65-80% of the cells in the islets.

Progenitor Cell is a biological cell that, like a stem cell, has a tendency to differentiate into a specific type of cell, but is already more specific than a stem cell and is pushed to differentiate into its "target" cell. The most important difference between stem cells and progenitor cells is that stem cells can replicate indefinitely, whereas progenitor cells can divide only a limited number of times. Controversy about the exact definition remains and the concept is still evolving. The terms "progenitor cell" and "stem cell" are sometimes equated.

Cellular Differentiation is the process where a cell changes from one cell type to another. Most commonly the cell changes to a more specialized type.

New technology to manipulate cells could one day help treat Parkinson's, arthritis, other diseases. DNA strands in materials act like traffic signals to start, stop cell activity or regenerate tissue. One of the findings is the possibility of using the synthetic material to signal neural stem cells to proliferate, then at a specific time selected by the operator, trigger their differentiation into neurons and then return the stem cells back to a proliferative state on demand. Spinal cord neural stem cells, initially grouped into structures known as “neurospheres,” can be driven to spread out and differentiate using a signal. But when this signal is switched off, the cells spontaneously re-group themselves into colonies.

Stem Cell Therapy is the use of stem cells to treat or prevent a disease or condition.


New stem cell method produces millions of human brain and muscle cells in days. The new platform technology, OPTi-OX, optimizes the way of switching on genes in human stem cells.

Regenerative Medicine is a branch of translational research in tissue engineering and molecular biology which deals with the "process of replacing, engineering or regenerating human cells, tissues or organs to restore or establish normal function". This field holds the promise of engineering damaged tissues and organs by stimulating the body's own repair mechanisms to functionally heal previously irreparable tissues or organs. Regenerative medicine also includes the possibility of growing tissues and organs in the laboratory and implanting them when the body cannot heal itself. If a regenerated organ's cells would be derived from the patient's own tissue or cells, this would potentially solve the problem of the shortage of organs available for donation, and the problem of organ transplant rejection.

Regeneration is the process of renewal, restoration, and growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. Every species is capable of regeneration, from bacteria to humans. Regeneration can either be complete where the new tissue is the same as the lost tissue, or incomplete where after the necrotic tissue comes fibrosis. At its most elementary level, regeneration is mediated by the molecular processes of gene regulation. Regeneration in biology, however, mainly refers to the morphogenic processes that characterize the phenotypic plasticity of traits allowing multi-cellular organisms to repair and maintain the integrity of their physiological and morphological states. Above the genetic level, regeneration is fundamentally regulated by asexual cellular processes. Regeneration is different from reproduction. For example, hydra perform regeneration but reproduce by the method of budding.
transforming human Scar Cells into Blood Vessel Cells

Endothelium is a type of epithelium that lines the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall. It is a thin layer of simple squamous cells called endothelial cells. Endothelial cells in direct contact with blood are called vascular endothelial cells, whereas those in direct contact with lymph are known as lymphatic endothelial cells. Vascular endothelial cells line the entire circulatory system, from the heart to the smallest capillaries. These cells have unique functions in vascular biology. These functions include fluid filtration, such as in the glomerulus of the kidney, blood vessel tone, hemostasis, neutrophil recruitment, and hormone trafficking. Endothelium of the interior surfaces of the heart chambers is called endocardium.

Adipose Tissue (fat)

Neural Crest cells are a temporary group of cells unique to vertebrates that arise from the embryonic ectoderm cell layer, and in turn give rise to a diverse cell lineage—including melanocytes, craniofacial cartilage and bone, smooth muscle, peripheral and enteric neurons and glia.

Activating the innate immune system opens up the DNA," said Cooke, the study's senior author. " This open state enhances the formation of induced pluripotent stem cells (iPSCs) or cells that can have the ability to regenerate into other cell types and tissues, such as that of the brain, heart or liver."

Bone Regeneration

Cell mechanism that transforms electrical signals into chemical ones explained. Electro-chemical coupling through protein super complexes: The calcium channel (Cav2) delivers calcium ions (Ca2+) that activate the enzyme NO synthase (NOS) for generation of the messenger NO. The enzymes nitric oxide (NO) synthase (NOS1) and protein kinase C (PKC) play an important role in a variety of signal transfer processes in neurons of the brain, as well as in many cell types of other organs. Enzymes can be activated under physiological conditions through sole electrical stimulation of the cell membrane. Protein super complexes that rapidly transform electrical signals at the cell membrane into chemical signal processes inside the cell emerge through direct structural interaction of both enzymes with voltage-gated calcium channels.


Eukaryote Organism is any contiguous living system, such as an animal, plant, fungus, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic size and are thus classified as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs.

Unicellular Organism also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of more than one cell. Historically, simple unicellular organisms have been referred to as monads, though this term is also used more specifically to describe organisms of the genus Monas and similar flagellate ameboids. The main groups of unicellular organisms are bacteria, archaea, protozoa, unicellular algae, and unicellular fungi. Unicellular organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms. Unicellular organisms are thought to be the oldest form of life, with early protocells possibly emerging 3.8–4 billion years ago.

Multicellular Organism are organisms that consist of more than one cell, in contrast to unicellular organisms. All species of animals, land plants and most fungi are multicellular, as are many algae, whereas a few organisms are partially uni- and partially multicellular, like slime molds and social amoebae such as the genus Dictyostelium. Multicellular organisms arise in various different ways, for example by cell division or by aggregation of many single cells. Colonial organisms are the result of many identical individuals joining together to form a colony. However, it can often be hard to separate colonial protists from true multicellular organisms, because the two concepts are not distinct; colonial protists have been dubbed "pluricellular" rather than "multicellular".

Eukaryote - Prokaryote

Anaerobic Organism is any organism that does not require oxygen for growth. It may react negatively or even die if oxygen is present. In contrast, an Aerobic Organism (aerobe) is an organism that can survive and grow in an oxygenated environment.

Microorganisms is a microscopic living organism, which may be single-celled or multicellular.

Model Organism is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms. Model organisms are in vivo models and are widely used to research human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms, and the conservation of metabolic and developmental pathways and genetic material over the course of evolution.

Biofilm is any group of microorganisms in which cells stick to each other and often these cells adhere to a surface. These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS). Biofilm extracellular polymeric substance, which is also referred to as slime (although not everything described as slime is a biofilm), is a polymeric conglomeration generally composed of extracellular DNA, proteins, and polysaccharides. Biofilms may form on living or non-living surfaces and can be prevalent in natural, industrial and hospital settings. The microbial cells growing in a biofilm are physiologically distinct from planktonic cells of the same organism, which, by contrast, are single-cells that may float or swim in a liquid medium. Microbes form a biofilm in response to many factors, which may include cellular recognition of specific or non-specific attachment sites on a surface, nutritional cues, or in some cases, by exposure of planktonic cells to sub-inhibitory concentrations of antibiotics. When a cell switches to the biofilm mode of growth, it undergoes a phenotypic shift in behavior in which large suites of genes are differentially regulated.

Biopolymer are polymers produced by living organisms; in other words, they are polymeric biomolecules. Since they are polymers, biopolymers contain monomeric units that are covalently bonded to form larger structures. There are three main classes of biopolymers, classified according to the monomeric units used and the structure of the biopolymer formed: polynucleotides (RNA and DNA), which are long polymers composed of 13 or more nucleotide monomers; polypeptides, which are short polymers of amino acids; and polysaccharides, which are often linear bonded polymeric carbohydrate structures. Cellulose is the most common organic compound and biopolymer on Earth. About 33 percent of all plant matter is cellulose. The cellulose content of cotton is 90 percent, for wood is 50 percent.

Biosynthesis is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. In biosynthesis, simple compounds are modified, converted into other compounds, or joined together to form macromolecules. This process often consists of metabolic pathways. Some of these biosynthetic pathways are located within a single cellular organelle, while others involve enzymes that are located within multiple cellular organelles. Examples of these biosynthetic pathways include the production of lipid membrane components and nucleotides. The prerequisite elements for biosynthesis include: precursor compounds, chemical energy (e.g. ATP), and catalytic enzymes which may require coenzymes (e.g.NADH, NADPH). These elements create monomers, the building blocks for macromolecules. Some important biological macromolecules include: proteins, which are composed of amino acid monomers joined via peptide bonds, and DNA molecules, which are composed of nucleotides joined via phosphodiester bonds.

Methanogen are microorganisms that produce methane as a metabolic byproduct in anoxic conditions.

Hypoxia (environmental) refers to low oxygen conditions. Normally, 20.9% of the gas in the atmosphere is oxygen.

Lithoautotroph is a microbe which derives energy from reduced compounds of mineral origin.

Lithotroph are a diverse group of organisms using inorganic substrate (usually of mineral origin) to obtain reducing equivalents for use in biosynthesis (e.g., carbon dioxide fixation) or energy conservation (i.e., ATP production) via aerobic or anaerobic respiration. Known chemolithotrophs are exclusively microbes; no known macrofauna possesses the ability to utilize inorganic compounds as energy sources.

Slim Mold The Blob can Learn - and Teach ! It isn't an animal, a plant, or a fungus. The Slime Mold (Physarum polycephalum) is a strange, creeping, bloblike organism made up of one giant cell. Though it has no brain, it can learn from experience, as biologists at the Research Centre on Animal Cognition. Imagine you could temporarily fuse with someone, acquire that person's knowledge, and then split off to become your separate self again, you don't have to imagine because that is what schools are supposed to do, but fail to understand the process.

A single-celled organism capable of learning

Habituation is a form of learning in which an organism decreases or ceases to respond to a stimulus after repeated presentations. Essentially, the organism learns to stop responding to a stimulus which is no longer biologically relevant. For example, organisms may habituate to repeated sudden loud noises when they learn these have no consequences. Habituation usually refers to a reduction in innate behaviours, rather than behaviours developed during conditioning in which the process is termed "extinction".

Organelles is a specialized subunit within a cell that has a specific function. Individual organelles are usually separately enclosed within their own lipid bilayers.


Bacteria constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep portions of Earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals.

Germs - Viruses

Cyanobacteria is a phylum of bacteria that obtain their energy through photosynthesis, and are the only photosynthetic prokaryotes able to produce oxygen. The name "cyanobacteria" comes from the color of the bacteria (Greek: κυανός (kyanós) = blue). Sometimes, they are called blue-green algae, and incorrectly so, because cyanobacteria are prokaryotes and the term "algae" is reserved for eukaryotes. Like other prokaryotes, cyanobacteria have no membrane-sheathed organelles. Photosynthesis is performed in distinctive folds in the outer membrane of the cell (unlike green plants which use organelles adapted for this specific role, called chloroplasts). Biologists commonly agree that chloroplasts found in eukaryotes have their ancestry in cyanobacteria, via a process called endosymbiosis. By producing oxygen as a byproduct of photosynthesis, cyanobacteria are thought to have converted the early oxygen-poor, reducing atmosphere, into an oxidizing one, causing the "rusting of the Earth" and the Great Oxygenation Event, that dramatically changed the composition of life forms and led to the near-extinction of anaerobic organisms.

Premordial Life or Abiogenesis is said to be a natural process of life arising from non-living matter, such as simple organic compounds. Primordial Soup is thought to have occurred on Earth between 3.8 and 4.1 billion years ago. How can abiogenesis be a natural process when you have no proof and no other planet to compare it to. Information does not come from nothing, this information had to originate from somewhere.

Archaea constitute a domain and kingdom of single-celled microorganisms. These microbes (archaea; singular archaeon) are prokaryotes, meaning that they have no cell nucleus or any other membrane-bound organelles in their cells.

Eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes belong to the taxon Eukarya or Eukaryota. The defining feature that sets eukaryotic cells apart from prokaryotic cells (Bacteria and Archaea) is that they have membrane-bound organelles, especially the nucleus, which contains the genetic material and is enclosed by the nuclear envelope. The presence of a nucleus gives eukaryotes their name.

Prokaryote is a unicellular organism that lacks a membrane-bound nucleus (karyon), mitochondria, or any other membrane-bound organelle.

Prokaryotic DNA Replication is the process by which a prokaryote duplicates its entire genome into another copy that is
passed on to daughter cells. Although it is often studied in the model organism E. coli, other bacteria show many similarities. Replication is bi-directional and originates at a single origin of replication (OriC). It consists of three steps: Initiation, elongation, and termination. DNA replication begins at the origin of replication, a region commonly containing repeating sequences (DnaA boxes) that bind DnaA, an initiation protein. DnaA-ATP will first bind high-affinity boxes (R1, R2, and R4, which have a highly conserved 9 bp consensus sequence 5' - TTATCCACA - 3'), then oligomerize into several low-affinity boxes. This accumulation will displace a protein called Fis, allowing another protein, IHF, to bind the DNA and induce a bend. This bend allows the DnaA chain to load onto an AT-rich region of 13-mers (the DUE, Duplex unwinding element), causing the double-stranded DNA to separate. The DnaC helicase loader will interact with the DnaA on the single-stranded DNA to recruit the DnaB helicase, which will continue to unwind the DNA as the DnaG primase lays down an RNA primer and DNA Polymerase III holoenzyme begins elongation.

Histology is the study of the microscopic anatomy (microanatomy) of cells and tissues of plants and animals.

Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy. Dormancy tends to be closely associated with environmental conditions. Organisms can synchronize entry to a dormant phase with their environment through predictive or consequential means. Predictive dormancy occurs when an organism enters a dormant phase before the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase after adverse conditions have arisen. This is commonly found in areas with an unpredictable climate. While very sudden changes in conditions may lead to a high mortality rate among animals relying on consequential dormancy, its use can be advantageous, as organisms remain active longer and are therefore able to make greater use of available resources.

Microfluorimetry is an adaption of fluorimetry for studying the biochemical and biophysical properties of cells by using microscopy to image cell components tagged with fluorescent molecules. It is a type of microphotometry that gives a quantitative measure of the qualitative nature of fluorescent measurement and therefore, allows for definitive results that would have been previously indiscernible to the naked eye.

Phylogenetic Tree is a branching diagram or "tree" showing the inferred evolutionary relationships among various biological species or other entities—their phylogeny—based upon similarities and differences in their physical or genetic characteristics. The taxa joined together in the tree are implied to have descended from a common ancestor. Phylogenetic trees are central to the field of phylogenetics.

New Updated Tree of Life

Phylogenetic Network is any graph used to visualize evolutionary relationships (either abstractly or explicitly) between nucleotide sequences, genes, chromosomes, genomes, or species. They are employed when reticulation events such as hybridization, horizontal gene transfer, recombination, or gene duplication and loss are believed to be involved. They differ from phylogenetic trees by the explicit modeling of richly-linked networks, by means of the addition of hybrid nodes (nodes with two parents) instead of only tree nodes (a hierarchy of nodes, each with only one parent). Phylogenetic trees are a subset of phylogenetic networks. Phylogenetic networks can be inferred and visualised with software such as SplitsTree and, more recently, Dendroscope. A standard format for representing phylogenetic networks is a variant of Newick format which is extended to support networks as well as trees.
Phylogenetic tree
Molecular Phylogenetics is the branch of phylogeny that analyses hereditary molecular differences, mainly in DNA sequences, to gain information on an organism's evolutionary relationships.

Molecular Systematics is the use of molecular genetics to study the evolution of relationships among individuals and species. The goal of systematic studies is to provide insight into the history of groups of organisms and the evolutionary processes that create diversity among species.

Porphyrian Tree is a classic device for illustrating what is also called a "scale of being" which indicates that a species is defined by a genus and a differentia and that this logical process continues until the lowest species is reached, which can no longer be so defined.

Tree of Life is a widespread mytheme or archetype in the world's mythologies, related to the concept of sacred tree more generally, and hence in religious and philosophical tradition.

Great Chain of Being is a strict, religious hierarchical structure of all matter and life, believed to have been decreed by God. The chain starts from God and progresses downward to angels, demons (fallen/renegade angels), stars, moon, kings, princes, nobles, commoners, wild animals, domesticated animals, trees, other plants, precious stones, precious metals, and other minerals.

Falsifying Phylogeny (youtube)

Parsimony is an optimality criterion under which the phylogenetic tree that minimizes the total number of character-state changes is to be preferred. Under the maximum-parsimony criterion, the optimal tree will minimize the amount of homoplasy (i.e., convergent evolution, parallel evolution, and evolutionary reversals). In other words, under this criterion, the shortest possible tree that explains the data is considered best. The principle is akin to Occam's razor, which states that—all else being equal—the simplest hypothesis that explains the data should be selected.

Binary Fission is the division of a single entity into two or more parts and the regeneration of those parts into separate entities resembling the original. The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts. The fission may be binary fission, in which a single entity produces two parts, or multiple fission, in which a single entity produces multiple parts.

Transitional Fossils is a tentative partial list of transitional fossils (fossil remains of groups that exhibits both "primitive" and derived traits). The fossils are listed in series, showing the transition from one group to another, representing significant steps in the evolution of major features in various lineages. These changes often represent major changes in morphology and anatomy, related to mode of life, like the acquisition of feathered wings for an aerial lifestyle in birds, or limbs in the fish/tetrapod transition onto land.

Horizontal Gene Transfer is the movement of genetic material between unicellular and/or multicellular organisms other than via vertical transmission (the transmission of DNA from parent to offspring.) HGT is synonymous with lateral gene transfer (LGT) and the terms are interchangeable. HGT has been shown to be an important factor in the evolution of many organisms. Horizontal gene transfer is the primary reason for the spread of antibiotic resistance in bacteria and plays an important role in the evolution of bacteria that can degrade novel compounds such as human-created pesticides and in the evolution, maintenance, and transmission of virulence. This horizontal gene transfer often involves temperate bacteriophages and plasmids. Genes that are responsible for antibiotic resistance in one species of bacteria can be transferred to another species of bacteria through various mechanisms such as F-pilus, subsequently arming the antibiotic resistant genes' recipient against antibiotics, which is becoming a medical challenge to deal with. Most thinking in genetics has focused upon vertical transfer, but there is a growing awareness that horizontal gene transfer is a highly significant phenomenon and among single-celled organisms, perhaps the dominant form of genetic transfer. Artificial horizontal gene transfer is a form of genetic engineering.

The tree of life does not say you grew out of bacteria, the tree of life is the biological history of planet earth, things that we have learned so far. The tree of life shows the path that certain information took, or transcended from. The tree of life shows some of the things that we and other life forms are made out of, not grew out of, but made out of. If you were creating advanced animal life, you would want animals made out of certain things like bacteria, things that have learned to survive for millions of years. This is more then a symbiotic relationship with microbes, this is the blueprint for life, use the strongest material available, give life the ability to adapt, to evolve and to learn. Intelligent Design

The responsibility of life is now in our hands. Humans have been given the ability to manually adjust information, which gives life even more chances to survive, pure genius. But it is also pure hell when the ability to manually adjust information causes death and destruction, all because the information being adjusted reduces our chances of survival, like pollution that poisons the water, land and air. There is also corruption. Bad information is cancer, actions being made based on bad information. Bad cells are multiplying when bad cells should be dying.
