Evidence for natural selection is both abundant and compelling. First, there is the taxonomy of species created by Linnaeus. This hierarchical system strongly implies modern species shared common ancestry, and it is this implication that prompted Charles Darwin to set out on his voyage on the Beagle. During that voyage Darwin encountered numerous fossils that helped him put forth and hone the theory of evolution. For example, Darwin noted fossils of extinct sloths, which highlighted the fact this species had undergone significant change over geologic time. Darwin was also aware that the earliest fossils were all "primitive" Cambrian marine organisms. It was apparent that at the earliest stages, there were no terrestrial life forms.
For natural selection specifically Darwin noted adaptations in varieties of pigeons introduced through artificial selection by pigeon breeders. He realized there was no reason nature could not produce similar variety through its own selection process, and the evidence of variation over geographical areas supports that.
Since Darwin's time we have developed techniques of molecular Biology and studies of embryology to further demonstrate the ancestral kinship shared by living organisms. Our own species, for example, shares a defect common to other primates (non functioning GULO gene which is responsible for the synthesis of ascorbic acid) almost no other mammal has. In addition, we can show that our chromosome number 2 is the result of the fusion of two primate chromosomes.
All of the scientific data comprises a veritable rock solid mountain of evidence detailing the pathways of evolution of the course of the past six hundred million years.
In the age old question "which came first the chicken or the egg," evolution points to the egg. As the years passed the egg changed by genetic mutation in the ancestors of the earliest chickens.
There are a number of evidences for evolution . Some evidences were provided by Darwin and some by others . Previously fossils were considered best evidence but now molecular biology is considered best .

Evolution.
Intelligent design, Hovind Theory Added: The above are not scientific theories but more ideological assertions in nature. No positive evidence supports either assertion.
supports hypothesis that species have changed over time.
that question is on the hw assignment I got today. I didn't really learn it or I wasn't paying attention and there's nothing online...
Because viruses are single-cell organisms, they can mutate (evolve) quicker than complex, multi-cell organisms, where evolution gradually happens over time spans that humans can hardly fathom. Viral mutations give evolutionary biologists the opportunity to observe the process within timespans a human being can grasp. It not only supports the theory of evolution, but confirms it with demonstrable evidence.
Because it does! Natural selection is the best explanation of adaptive change that we have and drives much of evolution. talkorigins.orgPS: Evolutionists is an ideological, not a scientific term
Yes, penguins, like all animals, have gone through natural selection. Scientific evidence supports this notion.
Because non-scientists do not understand what a scientific theory actually means. It is not a random guess. Scientific theories are formed based on evidence and experimentation.The scientific community advocates evolution because all the evidence of life on our planet supports the theory.

Scientific evidence appeal is some form of proof which supports or counters a scientific theory. This is the information that will be used as empirical evidence of a hypothesis.
There are plenty. Try the Wikipedia article on evolution, for example; it includes a list of scirntific sources and records which explain the evidence and how it supports the theory. Of course, you shouldn't need a website to tell you; just look at the evidence and there aren't many ways to explain it better (scientifically speaking; God is not scientific and therefore excluded from any scientific discussion of evolution).
Law and math prove things. Science supports tentative ( more or less ) explanations of natural phenomenon with evidence. The evidence overwhelmingly supports evolutionary theory. PS Evolution itself is a observed and observable fact.
Evolution.
An evolutionist is someone who believes in the scientific theory of evolution, which explains how species change and develop over time through natural selection and genetic variation. Evolutionists study the evidence supporting the theory, such as fossil records and genetic data, to understand the diversity of life on Earth.
