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.

Figure 2. Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia (long chronology, single source model). 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]
Two skulls suggested to belong to "Botocudo" people (a term used to refer to Native Americans who live in the interior of Brazil that speak Macro-Jê languages), were found in research published in 2013 to have been members of mtDNA haplogroup B4a1a1, which is normally found only among Polynesians and other subgroups of Austronesians. This was ...
The term Beringia was first coined by the Swedish botanist Eric Hultén in 1937. During Beringia's long history some animals migrated Easterly ( mastodons , gomphotheres , mammoths , various members of the deer family , bison , sheep and muskoxen ) others Westerly ( equines , camels ), and yet others reveal many episodes of dispersal (such as ...
Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia, from 25,000 years ago to present. The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas from about 20,000 to 14,000 years ago (20–14 kya), and European contact, after about 500 years ago.
The second and more important advantage geography gave to the northerners is related to the land area in which their ancestors evolved. During the Cenozoic, North America was periodically connected to Eurasia via Beringia, allowing repeated migrations back and forth to unite the faunas of the two continents.
In his thesis, he coined the term Beringia for the ice-age land bridge between Eurasia and North America. From 1945 to 1961, he was a professor and head of the Botany Section at the Swedish Museum of Natural History. In 1953, he was elected to the Royal Swedish Academy of Sciences as member number 977.
