Study the map.
A map of the North American continent contains arrows that show two possible migration routes of early humans to North America. The first arrow starts in Asia and moves over land into Alaska and Northern Canada, spreads throughout the United States, and into Mexico and South America. The second arrow starts in the islands of the Bering Sea and follows the coasts of Alaska, Canada, and the mainland of the United States, down along the coasts of Mexico and Central and South America.
