"It's the oldest archaeological site from the American southeast," anthropologist Michael Waters of Texas A&M University told reports on a telephone briefing. "Clearly humans were exploring and settling the Americas at this time" . . .
There are other sites in the continental U.S. that have also been dated to before 13,000 years ago, but only three, and they're all much further west - in Oregon, Wisconsin and Texas, and there is one site in Chile. DNA evidence suggests that humans were in the Americas long before even 14,550 years ago, but there is no physical evidence to support the idea.
