Peopling of the North Circumpolar Region - Insights from Y Chromosome STR and SNP Typing of Greenlanders.
Olofsson JK, Pereira V, Børsting C, Morling N.

Abstract
The human population in Greenland is characterized by migration events of Paleo- and Neo-Eskimos, as well as admixture with Europeans. In this study, the Y-chromosomal variation in male Greenlanders was investigated in detail by typing 73 Y-chromosomal single nucleotide polymorphisms (Y-SNPs) and 17 Y-chromosomal short tandem repeats (Y-STRs). Approximately 40% of the analyzed Greenlandic Y chromosomes were of European origin (I-M170, R1a-M513 and R1b-M343). Y chromosomes of European origin were mainly found in individuals from the west and south coasts of Greenland, which is in agreement with the historic records of the geographic placements of European settlements in Greenland. Two Inuit Y-chromosomal lineages, Q-M3 (xM19, M194, L663, SA01 and L766) and Q-NWT01 (xM265) were found in 23% and 31% of the male Greenlanders, respectively. The time to the most recent common ancestor (TMRCA) of the Q-M3 lineage of the Greenlanders was estimated to be between 4,400 and 10,900 years ago (y. a.) using two different methods. This is in agreement with the theory that the North Circumpolar Region was populated via a second expansion of humans in the North American continent. The TMRCA of the Q-NWT01 (xM265) lineage in Greenland was estimated to be between 7,000 and 14,300 y. a. using two different methods, which is older than the previously reported TMRCA of this lineage in other Inuit populations. Our results indicate that Inuit individuals carrying the Q-NWT01 (xM265) lineage may have their origin in the northeastern parts of North America and could be descendants of the Dorset culture. This in turn points to the possibility that the current Inuit population in Greenland is comprised of individuals of both Thule and Dorset descent.

Как, кстати, и C-P39.

Вот те и эскимосы.

Это - мелочь по сравнению с 85% европейских Y-DNA у алеутов.

... и почти наверняка подавляющее большинство у алеутов от русских....

...читаем в википедии...

С 1799 Алеутские острова и прилегающая к ним часть Аляски управлялись Российско-Американской компанией. Для освоения необитаемых Командорских островов компания переселила туда с этих островов часть алеутов, предков нынешних. В дальнейшем население Командорских островов пополнялось не только алеутами, но и креолами (потомками европейцев и алеутов) и русскими промышленниками из Атки и Калифорнии, женившимися на алеутках.

Prior to major influence from outside, there were approximately 25,000 Aleuts on the archipelago. Barbarities by outside corporations and foreign diseases soon reduced the population to less than one-tenth this number, The 1910 Census count showed 1,491 Aleuts. In the 2000 Census, 11,941 people reported they were of Aleut ancestry; nearly 17,000 said Aleuts were among their ancestors.  Alaskans generally recognize the Russian occupation left no full-blooded Aleuts. When Alaska Natives enrolled in their regional corporations under the terms of the Alaska Native Claims Settlement Act of 1971 (ANCSA), the Aleut Corporation attracted only about 2,000 enrollees who could prove a blood quantum of 1/4 or more Alaska Native (including Aleut).

Какие-то современные алеуты не те, что раньше...

the Russian occupation

[Srkz]

Креолы считались, скажем так, "негражданами" (промежуточной прослойкой между русскими служащими компании и местным населением), поэтому при передаче Аляски США их в Россию почти не вывозили.

the Russian occupation

Ну, так и было. С тлинкитами вообще воевать пришлось. Так что, таки да - оккупация Аляски русскими.

...так аляска до сих пор аккупирована не русскими... да вся америка тоже...

 Вы опять без фактов:

The majority of Aleut Y-chromosomes were characterized to haplogroups of mostly Russian, Scandinavian and Western European origin (approximately 85%), which is in stark contrast to the 3.6% of Aleut mtDNA lineages identified as non-Native American, and thus indicating a large degree of asymmetrical gene flow between European men and Aleut women.
