The Greatest Show on Earth Quotes by Richard Dawkins
Three Pieces of Evidence That Prove Evolution is a Fact
The theory of organic evolution seems to be the most acceptable explanation of the occurrence of varied forms of plants and animals on Earth. Evolution, which started out as a hypothesis, is now supported by evidence from many fields of science. The various convincing evidences for the occurrence of descent with modification is summarised in the Fig. The study of fossils is called palaeontology. Fossils not only refer to evidence of bones, teeth and other hard parts but to any impression or imprint by an organism in soft mud that subsequently hardens or moulds and casts of entire organisms. Most of the fossils are found in sedimentary rocks and are at least 10, years old. The study of fossils reveal the existence of life in the past and illustrates the course of evolution of plants and animals.
There are now numerous established pieces of evidence which support the theory of evolution by natural selection. Something provides evidence for evolution when it demonstrates a change in characteristics from an ancestral form. Fossil Record.

Evidence of Evolution
Fossils tell us when organisms lived, as well as provide evidence for the progression and evolution of life on earth over millions of years. Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. - The evidence for evolution is compelling and extensive.
The universal genetic code. All cells on Earth, from our white blood cells, to simple bacteria, to cells in the leaves of trees, are capable of reading any piece of DNA from any life form on Earth. This is very strong evidence for a common ancestor from which all life descended. The fossil record. The fossil record shows that the simplest fossils will be found in the oldest rocks, and it can also show a smooth and gradual transition from one form of life to another. Please watch this video for an excellent demonstration of fossils transitioning from simple life to complex vertebrates. Genetic commonalities.
For over years—since the time of Charles Darwin—the Theory of Evolution has been through more scrutiny and rigorous investigation than just about any other scientific claim. And the theory has only been strengthened as more evidence has been accrued. While there are many that people who, for ideological reasons, want to make it seem like evolution is not widely accepted within the scientific community, this is not actually the case. Indeed, the scientific fact that is evolution is the basis of most of biology. Think about your family.
