Genetic Analysis of Birnirk Inuit from the Alaskan North Slope
Archaeological evidence indicates that Birnirk peoples (AD 650 – 1300) are the proposed genetic ancestors of the Thule Inuit (AD 950 – 1400) and are potentially an intermediary population between the Thule Inuit and earlier Old Bering Sea people (AD 1 – 1000). We sequenced the first hypervariable re...

Archaeological evidence indicates that Birnirk peoples (AD 650 – 1300) are the proposed genetic ancestors of the Thule Inuit (AD 950 – 1400) and are potentially an intermediary population between the Thule Inuit and earlier Old Bering Sea people (AD 1 – 1000).
