[Aztlan] THE BULK OF THE AMERICAS POPULATED BY ONE SIBERIAN GROUP

[Dave Pentecost]

Pay no attention to the ALL-CAPS headlines. There are differing views
on this. Particularly recommended for a survey of dissenting opinion
and contradictory evidence is the book

"1491: New Revelations of the Americas Before Columbus" by Charles C. Mann

http://www.amazon.com/1491-Revelations-Americas-Before-Columbus/dp/140004006X
