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 ...
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.

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 ...
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 ...
In biogeography, a land bridge is an isthmus or wider land connection between otherwise separate areas, over which animals and plants are able to cross and colonize new lands. A land bridge can be created by marine regression, in which sea levels fall, exposing shallow, previously submerged sections of continental shelf; or when new land is ...
Until 11,000 BCE, the territory of the park was connected by a land bridge – known as "Beringia" – to North America.On the eastern side, in Alaska, is the Bering Land Bridge National Preserve, operated by the US National Park Service.
This is commonly referred to as the "Bering land bridge" and is accepted by most, though not all scientists, to be the first point of entry of humans into the Americas. There is a small portion of the Kula Plate in the Bering Sea. The Kula Plate is an ancient tectonic plate that used to subduct under Alaska. [9]
Bering Strait crossing. 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.
