Well, this thread was bound to come about, and who better to start it than me? A lot of people? Well, I guess you're right...

Anyway, I am a firm believer in Charles Darwin's Theory of Evolution. Amazingly, a lot of people are not.

First off, I'll say why I believe in evolution. The following are the most convincing points that I remember from my past year of high school:

[color=red]Fossil Records[/color]

Fossils are indisputable evidence that organisms have changed over time. You can clearly observe that newer fossils still retain some characteristics of older fossil remains. The evolution of humans can actually be traced back precisely, from a monkey man-like ape to ape-like man to the Australopithecus to Neanderthals to Cromagnon to the modern-day homo sapiens. The next point is kind of related.

[color=red]Comparative Anatomy[/color]

When dealing with comparing the bones of organisms, two terms come into play: homologous and analogous. Bones that are homologous demonstrate that the two organisms have a common ancestry, and therefore support evolution, whereas ones that are analogous are only similiar in fucntion and do not support evolution. For example, a horse's leg and a dolphin's fin are homologous; the structure of each bone closely resembles te other's, suggesting that both the horse and the dolphin evolved from a common ancestor.

[color=red]Comparative Embryology[/color]

Sadly, I can't find any pictures on this, but some were contained in my textbook that demonstrates comparative embryology. The embryos of all organisms, whether they be humans or fish or crocodiles, start out looking identical, no difference at all. That is some very convincing evidence.

[color=red]Comparative Biochemistry[/color]

The most common instance of this is the near-100% similarity of human DNA and chimpanzee DNA. Common ancestry can be determined by examining the DNA, proteins, and amino acids of two species.

So, that's all I have to say on that, or all I am willing to type. I'm sure someone will get into genetics and cross squares and what not. If so fine, if not then I guess that's fine too, but I'm sure as heck not doin' it. :)
