The ancestors of the American Indians were nomadic hunters of northeast Asia who migrated over the Bering Strait land bridge into North America probably during the last glacial period (11,500–30,000 years ago). By c. 10,000 bc they had occupied much of North, Central, and South America.

History has it that the Amerindians came from the continent of Asia “thousands of years ago.” They came in search of food. They crossed an ice passage called “the Bering Straight” that connected Asia to North America. That ice passage later melted. They wandered around and some of them settled in what is now Guyana.

The Amerindians settled throughout North America and they were known as the ancestors of the Red Indian tribes we know today, as well as of the Eskimos in the far north. Even though they were nomadic some still followed the settled agricultural pursuit and developed agricultural civilisations of their own.

American Indian, member of any of the aboriginal peoples of the Western Hemisphere. The ancestors of contemporary American Indians were members of nomadic hunting and gathering cultures. These peoples traveled in small family-based bands that moved from Asia to North America during the last ice age.

The ancestors of Native Americans used a single migration route, most likely through Beringia, and subsequently populated all of the Americas in a time range between 25,000 and 15,000 years ago. Possible contact between Native Americans and Polynesians dates back to 1,400 years ago.
