Beringia is named for the Danish explorer, Vitus Bering, and is also referred to as the Bering Sea Land Bridge. This 'bridge' existed during the last glacial maximum, approximately 14,000 years ago, when sea level was much lower and present-day Alaska and eastern Siberia were connected. The rise and fall of sea levels throughout the Pleistocene would have alternately exposed and submerged the low-lying landmass.
Exposure of the Bering Sea Land Bridge is significant for several reasons. Many archaeologists and anthropologists believe that the Americas were populated by people who migrated across the land bridge. In addition, many land animals may have been able to migrate through Beringia, including mammoths, muskox, and lemmings.
