The Ancient Beringian (AB) is a human archaeogenetic lineage, based on the genome of an infant found at the Upward Sun River site (dubbed USR1), dated to 11,500 years ago. [1] The AB lineage diverged from the Ancestral Native American (ANA) lineage about 20,000 years ago.
Based on DNA analysis of USR1, the Ancient Beringians are hypothesized to have split off from East Asians around 36,000 years ago, with continuous gene flow occurring until around 25,000 years ago. The Ancient Beringians are also hypothesized to have diverged from the ancestors of Native Americans around 22,000 to 18,100 years ago. [14]
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.

Experts were also able to use wider genetic evidence to establish that the split between the Northern and Southern American branches from the Ancient Beringians in Alaska only occurred about 17,000 and 14,000 years, [31] further challenging the concept of multiple migration waves occurring during the very first stages of settlement.
Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [2]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 ...
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.
Jacques Cinq-Mars Born: 1941/42 (died 27 November 2021, aged 79) was a Canadian archaeologist specializing in Canada, especially Yukon. [1] Cinq-Mars excavated the Bluefish Caves site in the Old Crow area from 1977 to 1987. [2]
The Ancient Beringian were a population of Paleo-Indians that diverged from other Native Americans about 20,000 years ago. Ancient Beringians migrated from Siberia across Beringia and into Alaska during the lithic stage sometime prior to 11,500 years ago. This is accurate, based on the actual article (see page 4 of the Nature article).
