影片内容介绍
剧情简介
The storm of controversy surrounding the population of the Americas. Who were the first Americans and where did they come from? The conventional view is that they arrived here around 13,500 years ago, but startling new archaeological discoveries suggest it may have been long before that. And experts are testing contentious theories regarding how they got here, including the idea of a dangerous canoe-born voyage from Asia down the west coat of the Americas, or even across the Atlantic from Europe.
Since 1932 and the discovery of ancient weapons at Clovis, New Mexico, the "Clovis-first" theory held that Ice Age big-game hunters entered the continent by crossing a land bridge that spanned the Bering Strait between Asia and Alaska. Then archaeologists discovered a problem: massive ice sheets blocked the way south, and the search for an alternative explanation began. NOVA investigates controversial clues, including finds in an Alaskan bear cave hinting at a west coast voyage, and a stone tool from Virginia claimed to be evidence of a landing from Europe. Then visit an extraordinary Clovis dig in Texas with nearly half a million artifacts, which points to a completely different solution to the puzzle.
Join archaeologists and other experts as they dig into prehistory and uncover a provocative Stone Age detective story.
