Q-B143 is primarily found among the indigenous peoples of the North American Arctic, Greenland, and Northeastern Siberia.
It exhibits high frequencies among the Eskimos of Alaska, Canada, and Greenland.
[2] Recent studies indicate that the previously reported Q-NWT01 in Greenland populations is more likely to belong to the subclade Q-B143.
[3][1] The oldest known example of Q-B143 was found in an Ancient Paleo-Siberian individual from the Duvanniy Yar site in northeastern Siberia, dating back approximately 10,000 years.
[4] A male from the Saqqaq culture, discovered in Greenland and dated to around 4,000 years ago, has been found to belong to the Q-B143 lineage.
