Eskimos are Indigenous peoples who have traditionally inhabited the circumpolar region from eastern Siberia, across Alaska , Canada, and Greenland.
There are two main groups that are referred to as Eskimo: Yupik and Inuit. A third group, the Aleut, is related. The Yupik language dialects and cultures in Alaska and eastern Siberia have evolved in place beginning with the original Eskimo culture that developed in Alaska. The earliest known Eskimo cultures were Pre-Dorset Technology, which appear to have been a fully developed Eskimo culture that dates to 5,000 years ago. They appear to have evolved in Alaska from people using the Arctic small tool tradition, who probably had migrated to Alaska from Siberia at least 2,000
