Role in Human Migration
Prehistoric human migration was greatly influenced by the last glacial period, known in North America as the Wisconsin glaciation. In the late Wisconsin era, a land bridge across the Bering Strait allowed the first humans to reach North America from Asia (an alternative theory is migration along the coast; see Settlement of the Americas). Human migration routes opened during interglacial periods in Europe and Asia as well.
