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. In the 21st century, human mitochondrial DNA (mtDNA) research on skeletal remains has seemed to show a genetic relationship between the Sadlermiut and various other related ethnic groups. An incorrect association led many to conclude the Sadlermiut were of Dorset and Thule ancestry due to apparent haplogroups A (46%) and D (54%) found in skeletal remains, attributed to the Thule (A 100%) and Dorset (D 100%) cultures respectively. This evidence, along with statistical differences, led to the errant belief that the Sadlermiut would have been remnants of the Dorset culture, with more recent gene flow from the Thule, providing further evidence for a cultural displacement between the two groups approximately one thousand years ago. Similarly, the same percentage of the presence of both haplogroup A and D was discovered among paleo-Aleut skeletal remains, while it also discovered D 27% and A 73% among the "Neo-Aleut" population. This inconsistency may be attributed to the fact that a population displacement did not occur within the Aleutian Islands between the Dorset and Thule transition, meaning that the Sadlermiut may have not in fact been the very last remnants of the Dorset culture. Further studies show there is no genetic evidence to show a direct Dorset ancestry, but there is evidence to show both cultures may have shared an earlier common Siberian ancestry. Lifestyle The Sadlermiut were a hunter-gatherer people whose subsistence relied primarily on fishing and caribou hunting, although they also hunted seals, polar bears, and walruses. Unlike the mainland Inuit, the Sadlermiut were reported to show very little interest in hunting whales and trapping and were thus of little use to traders who frequented Coral Harbour. In addition, the Sadlermiut often
