The New World's Founding Population
How many people made up the original group that crossed the Bering Land Bridge from Asia to make the New World their home? Approximately 70, says Jody Hey, Professor of Genetics at Rutgers University. By using a computation using genetic information to create models of population divergence, Professor Hey can not only determine how many, but when -- approximately 12,000 to 14,000 years ago -- the split occurred. This is roughly consistent with the dating for most of the archaeological evidence.
