first inhabitants of North America Siberia Bering land bridge Clovis culture Americas North America Athabaskans Aleuts Eskimos
The first inhabitants of North America migrated from Siberia, crossing the Bering land bridge and arriving in the present-day United States at least 12000 years ago; some evidence suggests an even earlier date of arrival. The Clovis culture, which appeared around 11000BC, is believed to represent the first wave of human settlement in the Americas. This was likely the first of three major waves of migration into North America; later waves brought the ancestors of present-day Athabaskans, Aleuts, and Eskimos.
