Europeans proved this beginning about 1492, in a large-scale experiment.
Still, I'm fascinated with the Aborigines and Neanderthals. I really think the Neanderthals have been shortchanged. I wish I knew more about them.
I am too. I have read a bit about both groups but still would love to know more. I think the DNA testing is our best source of data. Bones told us a lot, but the things now being done with DNA are making old bones obsolete (was that a redundancy?).
I think DNA will answer a lot of questions. I just hope scientists are open to all possibilities.
And thanks for not being a "mean" evolutionist! :)
