Land Bridge Theory
Students need to know about the land bridge theory, which states that the Native Americans migrated from Asia to North America across a land bridge during the Ice age following buffalo and mammoths.
During this time period, low temperatures caused large areas of water on earth to freeze and form glaciers. These glaciers caused the level of water in the ocean to drop. The land that once was under water became exposed creating a long land bridge that connected North America to Asia.
Various historians developed the theory that people may have crossed this land bridge from Asia into North America and then continued across North America and spread into South America following various herds of animals continually searching for food.
