On the number of New World founders

Jody Hey's "On the number of New World founders" reaches a surprising conclusion about the first wave of immigrants to the Americas. I would love to know what their names were.

His analysis suggests that only about 70 individuals left their ancestral Asian population (estimated at about 9,000 individuals) to reach America 7,000 to 14,000 years ago. Archaeological evidence places the earliest American inhabitants in the New World at around 14,000 years ago. Though Hey's estimates are more recent, they also indicate a high probability at this time period. With this new approach, researchers will be able to explore this and many other questions to fill in the details of the first American immigration.
