Arctic Region, North Pole, Arctic

The earliest inhabitants of North America's central and eastern Arctic are referred to as the Arctic small tool tradition (AST) and existed circa 2500 BC. AST consisted of several subsets, including Independence culture and Pre-Dorset culture. The Dorset culture (Inuktitut: Tuniit or Tunit) refers to the next inhabitants of central and eastern Arctic. The Dorset culture evolved because of technological and economic changes during the period of 1050-550 BC. With the exception of the Quebec/Labrador peninsula, the Dorset culture vanished around 1500 AD. Supported by genetic testing, evidence shows that Dorset culture survived in Aivilik, Southampton and Coats Islands, until the beginning of the 20th century.
Dorset/Thule culture transition dates around the 9th-10th centuries. Scientists theorize that there may have been cross-contact of the two cultures with sharing of technology, such as fashioning harpoon heads, or the Thule may have found Dorset remnants and adapted their ways with the predecessor culture. Others believe the Thule displaced the Dorset. By 1300, the Inuit, present-day Arctic inhabitants and descendants of Thule culture, had settled west Greenland, and moved into east Greenland over the following century. Over time, the Inuit have migrated throughout the Arctic regions of Canada, Greenland, Russia and the United States.
