Where did the Eskimos originate from? (scientific answers: names, dates, places)?

Question

some say Japan, China, Mongolia... are there any good books or educational media that explains this?

Answer 1

Look at the y-haplogroup and mt-haplogroup maps. They show
much about people's origins, but only roughly.

Answer 2

The Eskimo are closely related to the Chukchee people who live in the eastern part of Russian Siberia; also to the Aleuts who live in the Aleutian Islands of Alaska.

It appears that everyone in the world has ancestry that originated in Africa if you go back far enough in time. About 30,000 years ago two groups of people left Africa. One group headed for India, New Guinea and Australia; the other headed for Central Asia. All of Europe, Most of India, East Asia and North and South America were populated from Central Asia about 15,000 years ago. The ancestors of the Eskimos would have been some of them.

From eastern Siberia around 280 B.C., Eskimo hunters migrated across Alaska, northern Canada and eventually reached even Greenland around 1,000 A.D., the same time the Vikings were arriving there from Norway and Sweden. Sadly, the two peoples did not get along with each other very well after they met. Eventually, a mini-Ice Age eventually wiped out the Scandinavian (Viking) settlements in eastern Greenland (around 1350) while the Eskimos on the western side managed to hold out there because they were better adapted to the cold . Today, all of Greenland is Eskimo.

The Eskimos were apparantly afraid of the American Indians and this is why they did not move further south into Canada and the United States.

Answer 3

During the last two Ice Ages, roughly 10,000 & 32,000 years ago, the Bering Sea was frozen into a Land Bridge, allowing a series of migrations from Northeastern Asia to North America...

Among these "Asians", as there were no nations yet, groups splintered off into various directions. One group stayed in the Alaskan region to the north, and became Modern-Day Eskimos. Others migrated East & South, becoming American Indian tribes, and subsequently Central & South American civilizations...
