Approximately how many thousands of years ago did Native Americans cross the path from Asia and into America?

Answer 1

Approximately 20,000 years There were four main migrations.

Answer 2

This is debatable. There is something in archaeology called the "clovis wall". Basically a type of spear head known as the "clovis point" is used to determine when people first arrived in the Americas. These spear heads started showing up around 12,500 years ago and so many anthropologists believed that this is when people started arriving. Any find which seemed to pre-date this was met with staunch opposition by the academic community known as the "clovis wall".

However this wall is starting to crumble and some native Americans who had claimed their people arrived as much as 30,000 years ago are being at least somewhat vindicated by finds which suggest people were on this side of the world at least 20,000 years ago.

The method of arrival is often disputed. While some groups very likely did cross the Barring land bridge, some anthropologists theorize that some people arrived by boat, citing the fact that there was nothing to suggest it was impossible, and that it would have been much easier to travel by boat than land.

Answer 3

Good question! For a long time 11,000 years was the benchmark date, but that never explained how sites from Tierra Del Fuego to British Columbia all came from around the same time. Recent excavations in Canada and the American Midwest now suggest dates as early as 20,000 years or more!

Answer 4

In an Ice Age era... through Alaska today, when the two continents, Russia and America, are joined by ice. But who could say how many thousand of years... it could be in million of years ago and who knows the blending of species might have occurred as have happened in Africa.
