The common ancestor of humans, chimps, gorillas and the other great ape species is extinct. But keep in mind that the theory of evolution does not require the parent species to go extinct. A sub-population of an existing species can be separated geographically (say, by the collapse of a land bridge) and gradually evolve into a new species, while the rest of the population of that species continues to exist.
Proof please. Everything you state is just conjecture. In order to believe it, one must have faith that such a thing is true. Hmm, ok to teach evolution which requires faith but not ID? Double standard????
Please no more comments unless you provide me with scientific proof. Otherwise ID is just as possible as any of you or anybody else’s theories. The one that makes the most SENSE, however, would be ID, hands down. That’s why so many of you evolutionists are fighting tooth and nail to keep it out of the schools. And your intolerance for other theories is quite tiresome.
