The temporary land mass linking Siberia and Alaska that is thought to have allowed hunter-gatherers to migrate from Asia to North America was Beringia.
Explanation:
Beringia is the name of a non-existent or submerged land connection or "bridge" that existed during the Pleistocene Ice Age. During this period it provided a land connection between North America and Asia.
The Bering land bridge was important for the living world, because over 10,000 years ago, Homo sapiens emigrated from Asia to North America as far as Alaska and Siberia. The exact route they were heading is not clear, as archeological and other traces flooded after the end of the Ice Age and sea level rise.
