I agree that the "New World foods were only recently added to the human
diet" standpoint feels very eurocentric.

Here's a brief look at some of America's oldest found human fossils (Luzia,
Kennewick Man, Spirit Cave Man), for those newbies who are interested.

Luzia is believed to be 11,500 years old. That would make her "upper paleo".
Why scientists insist on figuring out where, when, how, why and *who* first
immigrated to the Americas is beyond me. Perhaps Luzia's ancestors had been
in South America for thousands of years. We can't prove that they were, but
we also don't *know* that they weren't.
