Answer:
The Bering Land Bridge.
Explanation:
Alaska and Asia are separate now, but during the ice age, the situation was not the same. Approximately 20,000 years ago, large areas of the continental shelf were exposed, and sea levels dropped because the water was locked up in glacial ice. Thus forming the Bering Strait land bridge that connected Asia and Europe to North America. Early humans may have migrated across this land bridge. Humans began to migrate across the bridge about 12,000 Years ago, and it is believed that they were following migrating mammals. The landmass was approximately 2,000 kilometers wide across the Bering Strait and connected Siberia, and Alaska much of what is known about this land bridge comes from bio-geographical evidence showing connections between species on Asia and North America.
