Detailed explanation-2: -As of 2008, genetic findings suggest that a single population of modern humans migrated from southern Siberia toward the land mass known as the Bering Land Bridge as early as 30, 000 years ago, and crossed over to the Americas by 16, 500 years ago.

Detailed explanation-3: -Scientists one theorized that the ancestors of today’s Native Americans reached North America by walking across this land bridge and made their way southward by following passages in the ice as they searched for food.
