Although no one knows exactly when or how people crossed into North America, evidence suggests that people called Paleo-Indians crossed this bridge into Alaska between 38,000 and 10,000 BC. This migration — a movement of people or animals from one region to another—took place over a long time. It is believed that Paleo-Indians traveled south into Canada, the United States, and Mexico following herds of animals. Over time, their descendants went as far as the southern tip of South America. These people were hunter-gatherers , people who hunted animals and gathered wild plants for food. 6 CHAPTER 1 DO NOT EDIT--Changes must be made through “File info” CorrectionKey=TX-A Land Migrations of Early Peoples ASIA 180˚ 0˚ HRW US History t 170˚W ai tr ah06se_c01loc003aa S 160˚W ng eri 10˚W Migrations Locator B 150˚W 70˚N F1 proof 10/04/04 140˚W 20˚W 130˚W Approved 10/28/04 e l c About 8000 BC, ir C c ALASKA ti Earth’s climate grew rc A 30˚W warmer, and the Ice Age ended.
