Interesting.

I'd like to see what data correlation develops. While I personally believe that the Americas were settled long before 20,000 BP, I firmly believe they were settled by homo sapiens. When you hit the 80,000 year mark, you're hitting very early h.sap, and at the 1 million year mark you're hitting h. erectus.

We should see an entirely different species here in the Americas if this were fact.
