Thanks BenLurkin. Weekend comes early for the weekly Digest ping list!
ts highly unlikely that this population sailed from Australia or Indonesia to South America. Rather, this group likely trekked northward from their point of origin, venturing through China and Siberia.
It's highly unlikely that the writer of the article, and/or his academic sources, have any idea what they're talking about, vis a vis how populations moved around in the past, even the distant past. Also, it's problematical at best to try to figure out chronology from biology.
My jaw just hit the floor.
