in what year did the paleo Indians spread throughout America
The paleo-Indians probably entered north America by crossing a land bridge spanning which body of water?
The generally excepted theory is that the Paleo-Indians first arrived in North America by crossing the Bering Land Bridge about 13,000 to 10,000 years ago. This was during the last Ice Age, and because so much water was frozen in glaciers on land, the sea level was lower. This exposed the sea floor between Alaska and Russia, and allowed the Paleo-Indians to cross to North America, as well as a wide variety of other animals.
