The Eskimo-Aleut language phylum is distributed from coastal Siberia across Alaska and Canada to Greenland and is well distinguished from the neighboring Na Dene languages. Genetically, however, the distinction between Na Dene and Eskimo-Aleut speakers is less clear.

Eskimos
28 September 2005The core of the genetic makeup of the Chukchi and Siberian Eskimos consisted of three (Haplogroup A, Haplogroup C, and Haplogroup D) of the four primary mtDNA haplotype groups (Haplogroup A, Haplogroup B, Haplogroup C, and Haplogroup D) observed in Native Americans.
Haplogroup A being the most prevalent in both Chukotkan populations.
Two unique haplotypes belonging to Haplogroup G (formerly called "other" mtDNAs) were also observed in a few Chukchi, and these have apparently been (...) -
Aleuts
28 September 2005The Aleuts are aboriginal inhabitants of the Aleutian archipelago, including Bering and Copper (Medny) Islands of the Commanders Islands.
They seem to be the survivors of the inhabitants of the southern belt of the Bering Land Bridge that connected Chukotka/Kamchatka and Alaska during the end of the Ice Age.
Sireniki Eskimos in Chukotka belong to the Beringian-specific subhaplogroup D2.
Unlike the Eskimos and Na-Dene, the Aleuts of the Commanders were founded by a single lineage of (...) -
