Evolution

It has adaptations

There is plenty of fossil records and observable speciation to provide evidence for Evolution. Within the scientific community there is little to no debate on whether evolution is wrong. No concrete evidence has been provided by anyone to dispute the claims of evolution since its formulation by Darwin, otherwise it would have been discarded through the scientific method.

While the above is right, observation and scientific studies provide evidence and arguments to the theory.

No. Evolution is based on empirical, scientific data. It is in no way a merely social philosophical construct. The conjecture was founded upon hard physical evidence, and was built into a solid, robust theory, which now forms the foundation tying all the biological sciences together into one unified whole.

Evolution underpins biology the way the plate tectonics underlies geology.

A fat cells primary function is to store fat, quite simply. But recent discoveries show that the fat cell also produce the hormone leptin which decreases appetite. This means that fat cells play a role in food intake as a homeostatic mechanism. Also brown fat cells, which are present in babies and antarctic sea creatures, have an interesting function. The mitochondria in them are slightly modified not to have a specific protein that makes ATP from ADP and Pi using energy from H ions moving through the membrane. Instead these H ions move t via another protein which instead of ATP produces heat directly. And thus brown fat actually produced heat, is not just an insulator.

No facts currently known to science contradict the fundamental theses of evolutionary theory.

The Endosymbiotic Theory is a theory about how mitochondria and chloroplasts formed. The theory suggests that both the mitochondria and chloroplasts were once prokaryotic cells that were ingested but not digested by eukaryotic cells. This would explain why both have their own DNA.

Chemical evolution is thought to have caused the first cells to spontaneously generate over a very long period of time.

In science books or on the internet.

Evolution is simply a fact of nature, and a collection of mechanisms to explain that fact.

It says nothing about philosophy or morality or any other abstract human ideas about purpose or liberation (although some certainly try to make it).

If you think you can live your life your way, then do it. Evolution will not help you, but neither will it stop you; it simply doesn't matter.

Darwin established the theory of natural selection (evolution). On the Galapagos Islands he was fairly free to walk among animals previously unexposed to humans, thus seeing him as no threat. He observed: (1) more offspring were produced than would survive based on the available resources (food, water, space), (2) the offspring varied in form and had a range of characteristics, (3) the offspring would compete for the available resources. Darwin concluded that the creatures that were best suited to a particular environment would survive long enough to reproduce and pass their characteristics to a new generation. This is evolution. "Survival of the fittest" is actually shortened from the phrase, "survival of the fittest in a particular environment". Individual creatures don't evolve. Species evolve. A species is a group of organisms capable of breeding and producing offspring. Evolution drives the creation of new species. No organism is more or less evolved than another. One organism may be more suited to survive in a particular environment.

Darwin's theory was accepted,at first Darwin himself did not publish his findings as he did not feel anybody else would agree with his findings but once he found that a fellow scientist had conducted the same research and was going to publish his findings Darwin then also decided that he would publish his findings also.

The first oxygen on earth was produced by a blue green bacteria called cyanobacteria. They had no used for it, it was just waste in their process of making glucose as food using sunlight (the glucose was then fermented when the energy was needed). The waste oxygen poisoned many life forms. Eventually some life forms evolved that could use oxygen and also protected themselves from its poisonous character.

The political climate affects many people. They don't like how Democrats, Republicans and the Tea Party has split the nation.

Fossils give a record as to what organisms lived throughout different time periods. Generally speaking, the lower layers of soil show the oldest fossils, which aids scientists in following the progression of evolution of an organism. Also, radioactive carbon dating is used in dating how old a fossil is by finding the amount of carbon^14, and then calculating how many half lives have passed to reach this amount.

A cDNA (complementary DNA) library is a DNA library that has been created from mRNAs that are present in the cell. Since a cDNA is created from mRNA transcripts, that means that in Eukaryotic organisms there will be no introns or transcriptional factors present in the cDNA library, only exons. Only protein coding regions will be present in a cDNA library. This also means that a cDNA library is often times tissue specific. Since the expression of mRNAs will be different in different tissues of the organism it will appear different then a genomic library. Often times to offset this problem a cDNA library will be composed of different tissues (brain, liver, heart) to encompass a greater variety of the proteins that are expressed. A genomic library will contain all the exons, introns, and transcriptional factors that are not found in the cDNA library.

cDNA library does contain exons, which is the protein coding regions.

There isn't, of course, a gap in time. There are, however, very few fossils intermediate between simple stromatolites (the first more or less multicellular organisms) and the first complex organisms found just before the Cambrian Explosion. This gap most likely exists because while predation already existed (organisms consuming other organisms), no organisms had yet developed an internal or external skeleton that could have been preserved at death. The very few organisms from that era that were preserved despite of this, were preserved in the form of molds and casts.

They must help the organism in it'senvironmentso it may survive andreproduceand pass the trait down. If the trait is undesirable or useless the trait is selected against. Like if the desert was covered in snow, and all the 'prey' animals were out and wondering around. They can see if a 'predator' is coming, because of their orange-light brown color cause it doesn't blend in with the surrounding it isn't goodcamouflage.

Sceptile.

A mechanism (most common) of natural selection where overall genetic diversity decreases due to particular trait or genotype getting 'fixed' into the population. It is usually represented as a parabola on a graph.
