The Sadlermiut are most often cited for having maintained a unique culture and dialect apart from other Inuit, similar to the Unangam (Aleut), which is principally the result of an adaptation to environmental and historical constraints, whereas they show a closer genetic profile to paleo-Eskimo groups than neo-Eskimo groups. Because of this, various theories have been established to try to explain the Sadlermiut's cultural differences. One of these has tried to establish a clear link between the Sadlermiut as direct descendants of the Dorset culture. Another theory explains that rather than being related to the Dorset, the Sadlermiut were in fact descendants of the Thule, whose geographically isolated culture would have developed idiosyncratically from the mainland Thule culture. A third theory indicates that the Sadlermiut did not necessarily belong to either group, but because of intermarriage, their roots may have in fact been part of both Dorset and Thule cultures.
