HOW DID THE FIRST AMERICANS GET HERE?

People from Berengia moved to North America.

Where did the water in the Bering Strait go?

Huge glaciers more than a mile thick

Extended as far South as Illinois and Ohio

Earth’s waters were turned to ice, dropping the oceans to hundreds of feet below current levels

Receding waters created a land bridge

Refuges are formed due to glaciers

Humans first migrate to South America along the Eastern coast.

The Bering Strait reopens.

Debate over Migration

1. One Migration across Bering Strait

2. *Series of migrations and means of arrivalWater travel and “land crossings”

The ancestors of Aleuts, Eskimos, Na-Dene people arrive. Central Canada was populated.
