text: Archaeological findings Frozen remains of a Saqqaq person dubbed "Inuk" were found in western Greenland (Qeqertarsuaq) and have been DNA sequenced. He had brown eyes, black hair, and shovel-shaped teeth. It has been determined that he lived about 4000 years ago, and was related to native populations in northeastern Siberia. The Saqqaq people are not the ancestors of contemporary Kalaallit people, but instead are related to modern Chukchi and Koryak peoples. It is not known whether they crossed in boats or over ice.
  Saqqaq people lived in small tents and hunted seals, seabirds, and other marine animals.
  The people of the Saqqaq culture used silicified slate, agate, quartzite, and rock crystals as materials for their tools.
  Genetics
  A genetic study published in Science in August 2014 examined the remains of six Saqqaq individuals buried in Qeqertasussuk, Greenland between ca. 3000 BCE and 1900 BCE. The five samples of mitochondrial DNA (mtDNA) extracted belonged to haplogroups D2a1 (four samples) and D2a. These haplogroups also predominate in the Dorset culture, and are today found in high frequencies among Siberian Yupik and Aleut, with whom the Saqqaq are relatively closely related. The evidence suggested that the ancestors of the Saqqaq entered North America from Siberia through a distinct migration about 4000 BC, and that they subsequently remained largely genetically isolated from other North American populations.
