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 ...
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 ...
The ancestors of today's American Indigenous peoples were the Paleo-Indians; they were hunter-gatherers who migrated into North America. The most popular theory asserts that migrants came to the Americas via Beringia , the land mass now covered by the ocean waters of the Bering Strait .
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.

Starting the Paleo-Indigenous American period, a migration to the Americas across the Bering Strait by a small population carrying the Q-M242 mutation occurred. [15] A member of this initial population underwent a mutation, which defines its descendant population, known by the Q-M3 (SNP) mutation. [60]
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.
During winter, the Bering Strait has historically been blanketed in ice. But this year, the ice has nearly vanished. "The usually ice-covered Bering Strait is almost completely open water," Zack ...
This timeline is an incomplete list of significant events of human migration and exploration by sea. This timeline does not include migration and exploration over land, including migration across land that has subsequently submerged beneath the sea, such as the initial settlement of Great Britain and Ireland .
