You may have missed the point of my participation here. I'm accepting Vade's challenge. He said that a creationist can't pretend to be an evolutionist, and I'm doing my best to demonstrate that I can recite the evolutionist's dogma, and even do so with a degree of comprehension. So in that mode, my answer to you would be: "Yes, certainly," but in reality, I don't think it means anything more than the fact that a palm tree can't generate vitimin C either, and I'm no kin to the palm tree. Nor are you, I assume.
Amazing. The exact same mutation, just, happened, and by some kind of coincidence, just happened in species that were already thought to be related on anatomical grounds.
