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 ...
The Bering Sea is named after Vitus Bering, a Danish-born Russian navigator, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean. [6] The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula.
Satellite image of Bering Strait. Cape Dezhnev, Russia, is on the left, the two Diomede Islands are in the middle, and Cape Prince of Wales, Alaska, is on the right. The Bering Strait is about 82 kilometers (51 mi) wide at its narrowest point, between Cape Dezhnev, Chukchi Peninsula, Russia, the easternmost point (169° 39' W) of the Asian continent and Cape Prince of Wales, Alaska, United ...
Dating the initial coastal migration is challenging because of the flooding of early settlement sites by the rise of the eustatic sea level accompanying deglaciation. Dates for sites such as ones at Ground Hog Bay in SE Alaska (10.2 ka) and Namu, about 800 km south of Ground Hog Bay near modern Bella Coola (9.7 ka) thus represent early mainland settlement above the present-day sea level after ...
About 10 billion snow crabs disappeared from the Bering Sea between 2018 and 2021. A recent study concluded that warmer water temperatures helped drive the crabs to starvation.
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.

Warmer, ice-free conditions in the southeast Bering Sea are roughly 200 times more likely now than before humans began burning planet-warming fossil fuels. Scientists have more evidence to explain ...
Examples of Clovis and other Paleoindian point forms, markers of archaeological cultures in North America. The Solutrean hypothesis on the peopling of the Americas is the claim that the earliest human migration to the Americas began from Europe during the Solutrean Period, with Europeans traveling along pack ice in the Atlantic Ocean.
