American Indians’ ancestors most likely came from ?
I'm sorry... I meant to add a link but clicked in the wrong place. Here's a link to use:
The answer to this is that the ancestors of the Native Americans most likely came to the Americas from Siberia.
The current belief is that the ancestors of the Native Americans lived in Northeast Asia around the time of the last Ice Age. When the Ice Age was at its peak, there was a land bridge where the Bering Strait is today. The ancestors of the Native Americans either came across the land bridge on foot or were able to go along its coast (or across the strait when it was much narrower than today) in boats.
