Predators are just one environmental pressure for natural selection. There are tons of others, from ecological (weather, temperature) to behavioral (mating traits, etc.). Mutations are actually the biggest driving force of genetic variation, but natural selection ensures that beneficial mutations spread.Originally Posted by rubah
You mean beyond everything we know about biology? Our own bodies, from anatomy to genetics? How does creationism explain the fact that the mitochondria in our cells has its own DNA and looks suspiciously like an ancient bacteria (which, according to a universally accepted theory, began a symbiotic relationship with our multi-cellular ancestors hundreds of millions of years ago). Since I take it you haven't actually cracked a textbook, talkorigins is an excellent resource to catch you up to speed.Originally Posted by Mercen-X
