A fascinating glimpse at the first Americans via genetics. They crossed the Bering Strait and shot off in all directions. A body from Nevada turns out to be very closely related to a body found in Brazil, across the equator…a few hundred years later. Close relationships were found between people who lived 10,000 years apart.
