The Inuit tribe descended from ancient tribes that crossed the Bering Strait into North America between 1000 and 6000 B.C. Anthropologists believe that the Inuit evolved from the ancient Denbigh civilization that had adapted to living by the ocean and in arctic conditions.
Characteristics of the ancient Denbigh people include the use of small tools and skin-covered boats. By 1000 B.C., the Denbigh evolved into the Dorset and Thule cultures that spread across the Arctic regions of Canada and Greenland and share many characteristics of the Inuit, such as the use of dog-sleds, kayaks and harpoons for hunting whales. The Inuit were primarily nomadic and divided the year into hunting season for seals, caribou, elk and whales. The oldest permanent Inuit settlement is in the town of Point Hope in Alaska and is at least 2,000 years old.
