Description

At one time, experts agreed that the first Americans walked across the Bering land bridge from Asia approximately 12,000 years ago, eventually colonizing all of North and South America. But exciting recent finds on both continents have triggered entirely new theories. In Coming to America, a part of the PBS Scientific American Frontiers series, host Alan Alda heads back to the past by exploring ancient finds alongside archeologists, like the Arlington Springs Woman - the oldest securely dated human remains - and the Clovis People, who were believed to have lived more than 13,000 years ago. The program explores newly surfaced questions, like were the first Americans actually from Europe? And, by what means did they arrive? There is no lack of intrigue, as the program presents a provoking selection of theories on who believes what...and why.
