该课题组人员发现了不同的地区种群，并发现了两次狗与加拿大因纽特人一起迁徙到格陵兰岛的证据。
此外，课题组研究人员还发现，尽管杂合度较低，但在今天的Qimmit中，欧洲祖先很少，最近的近交也有限。这些见解对于在环境变化和文化转型中保护Qimmit的保护工作至关重要。
研究人员表示，Qimmeq（格陵兰雪橇犬）在格陵兰岛与因纽特人一起工作了800多年。然而，由于气候变化、城市化和雪地车的竞争，它们现在面临着急剧的人口下降。这项研究对92个现代和古代基因组进行了测序，以调查几个世纪的隔离如何塑造了该地区的奇梅克族人口，以及与欧洲人接触的影响。

Abstract: The Qimmeq (Greenland sled dog) has worked continuously with the Inuit in Greenland for more than 800 years. However, they now face drastic population declines caused by climate change, urbanization, and competition from snowmobiles. This study sequenced 92 modern and ancient genomes to investigate how centuries of isolation shaped the regional Qimmeq populations and the impact of European contact. We found distinct regional populations and evidence for two migrations of dogs into Greenland with the Inuit from Canada. Furthermore, we found that there is minimal European ancestry in present day Qimmit and limited recent inbreeding despite low heterozygosity. These insights are critical for conservation efforts aimed at preserving the Qimmit amid environmental changes and cultural transitions.
