Furthermore, I might have put this in another thread but its more relevant here than there. Newton, Mendel and Darwin (and the other guy who i forget that never gets the credit darwin does) all had great launch-point ideas. Their theories upon testing have been incomplete. That's what science does. It tests and tries to see if there's any other option. Just as matter is not always conserved via newton (sometimes it gets turned into energy b/c they're the same thing) and mendel didnt count for masked expressions, plietropy etc Darwinian evolution had some gaps that were unable to be filled with the current technology at the time. It was once thought that evolution was towards perfection. This is now just about 100% agreed on to be false. Take an embriology class before talking about a fetus not being similar to another species at certain times. Read up on the article posted above and it will say things much better and more clearly than i believe I could.
