The Bering Strait has been the subject of the scientific theory that humans migrated from Asia to North America across a land bridge known as Beringia when lower ocean levels – a result of glaciers locking up vast amounts of water – exposed a wide stretch of the sea floor, [1] both at the present strait and in the shallow sea north and ...
Beringia sea levels (blues) and land elevations (browns) measured in metres from 21,000 years ago to present. Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72° north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula.

Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [1]The peopling of the Americas began when Paleolithic hunter-gatherers (Paleo-Indians) entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the ...
North Pole view of the Bering Strait. A Bering Strait crossing is a hypothetical bridge or tunnel that would span the relatively narrow and shallow Bering Strait between the Chukotka Peninsula in Russia and the Seward Peninsula in the U.S. state of Alaska. The crossing would provide a connection linking the Americas and Afro-Eurasia.
During the glacial epoch this bridge was a migration route for people, animals, and plants whenever ocean levels fell enough to expose the land bridge. [5] Archeologists disagree [6] whether it was across this Bering Land Bridge, also called Beringia, that humans first migrated from Asia to populate the Americas, [5] [7] or whether it was via a ...
Since they propagated across both sides of the Bering Strait before Beringia would disappear for the last time, we can reliably witness how isolation and environmental factors can splinter one ...
[1] [2] This hypothesis contrasts with the mainstream academic narrative that the Americas were populated first by people crossing the Bering Strait to Alaska by foot on what was land during the Last Glacial Period [3] or by following the Pacific coastline from Asia to America by boat. [4]
Although it is popularly agreed among archeologists that early settlers had crossed into Alaska from Russia through the Bering Strait land bridge, the issue of whether or not there was one founding group or several waves of migration is a controversial and prevalent debate among academics in the field today.
