“This fossil proves nothing, it sure doesn’t give evidence that so called “lucy” is an human ancestor.”
Both modern humans and ´Lucy´ are/were bipedal. You do realise how rare bipedalism is in nature don´t you?
Seemingly not that rare. There is this foot-bipedal. "Lucy"-bipedal. And as the anti-Lucarians insist the Hadar knee-joint did not come from "Lucy", that makes a third bipedal species from the same time, same place. (Unless of course, they actually belong together)
Yeah and that only shows that God uses what works, it doesn’t come close to proving the “lucy” anthropology line..
