There's Evidence for Evolution? (Link leads you back to the earlier information on this topic; if a field of evidence isn't found here, re-navigate to that page)

__//**C. Can evolution be seen before the birth of an organism?**//__ Similar organisms go through almost similar embryonic development. Embryos of similar vertebrates are also similar as they give a superficial appearance of relationship. However, a German biologist, Ernest Haeckel proposed that embryos in early stages do not look alike and made a fake drawing to prove his point! (Very Sad and unethical, right?)

All living organisms contain inherited genes and particular combinations of these genes (basically identical or similar segments of DNA molecules in cells). Since all proteins are made out of 20 different amino acids, the language of the DNA code is the same for all living organisms despite the great diversity of life present on Earth. In fact, all aerobic organisms contain the polypeptide //cytochrome c.// which even makes the organisms even more closely related. For example, chimpanzees and gorillas are closely related to humans as the cells containing //cytochrome c//. are very identical.
 * //__D. What about similarities in molecular biology?__//**

Biogeography is a very important factor and a major piece of evidence about evolution as the geographic distributing of organisms affects evolution. According to the //theory of continental drift//, all the continents were joined together in a single super continent called Pangaea. Over time, our present-day seven continents slowly separated from each other as they lie on seven large crustal plates studied in a field known as plate tectonics. Similar organisms and plants have been found at the edge of the continents to prove the theory of continental drift. Organisms that have evolved in isolation after the areas have been separated have become unique to those areas as continental drift played a major role in the evolution of different organisms.
