"Where did the Native Americans come from in America?

Most archaeologists and anthropologists suggest that the ancestors of Native Americans arrived in America from Asia, crossing the Bering Land Bridge that connected Asia and North America during the last ice age, approximately 14,000 to 20,000 years ago, or by boat across the Bering Sea.

In fact, a DNA test revealed that nearly all Native Americans could be descendants of four women who migrated from Asia to America around 20,000 years ago."
