When did human beings first settle in North America?

The date of the first human migration to the Americas is still in dispute.

It may be as early as 35,000 years ago or, according to some archeologists, no more than 12,000 years ago.

Whichever date turns out to be correct, it is believed that the first Americans migrated from northeastern Siberia across the Bering Strait, then a land bridge.
