NOVA follows the trail of America's first inhabitants. Did they migrate across a Bering Sea land bridge at the end of the last Ice Age, as we all learned in school? Or did they arrive thousands of years earlier, possibly by some different route, as new archaeological evidence increasingly hints?
Seen in more than 100 countries, NOVA is the most watched science based television series in the world and the most watched documentary series on PBS. It is also one of television's most acclaimed series, having won many major television awards, most of them many times over.
