Answer 2

Answer:

June 27, 2012 — -- A serendipitous discovery on a remote island off the coast of Alaska may provide a turning point in the debate among scholars over how the First Americans arrived in the new world.

For decades, archaeologists have believed that early hunters traveled across a wide swath of land that linked Siberia with Alaska during the last Ice Age, moved down into the Great Plains and eventually populated the New World.

But there's a problem, according to many scholars. The only route from the far north to what is now the continental United States was through a corridor between two huge ice fields that spanned the eastern and western regions of the continent. That corridor probably didn't thaw enough for human passage until about 13,000 years ago, and some well documented settlements in South America are believed to be at least 14,000 years old.
