Naked Science - Prehistoric Americans
Seizoen: 4 - Aflevering: 5 / 55 - Eerst uitgezonden: 14 maart 2007 - Episode ID: 458901
It has long been said that the first Americans were hunters who arrived on the continent some 13,500 years ago via the Bering land bridge. This idea is now being challenged by scientists using modern, high-tech forensics to arrive at a new conclusion; the first residents may have arrived thousands of years earlier and had a more developed grasp of engineering that we had thought possible.
