Eskimo–Aleut languages
According to Flegontov et al., the later Old Bering Sea archaeological culture came as a result of back-and-forth migrations across the Bering Strait by the tribes associated with the Arctic Small Tool tradition, or their descendants (Old Whaling, Choris, Norton culture, from 3,100 to 2,500 cal. yr BP). These peoples were mixing with the Chukotko-Kamchatkan speakers of Siberia. Eventually, the Old Bering Sea archaeological culture became the ancestor of the Yupik and Inuit, the speakers of Eskimo–Aleut languages.
