Genetic Analysis of Prehistoric Canis Remains from Across the North American Arctic: Implications for Interactions Among their Human Companions

鉴于狗对北方文化的重要性及其与人类的交织关系，本研究项目旨在解决与狗从亚洲到阿拉斯加和加拿大/格陵兰的时机和传播以及当地品种发展有关的问题。利用现代遗传学方法从考古年代久远的牙齿和骨骼遗骸中提取DNA，并结合放射性碳测年和最近样本的分析，私人投资者建议(1)对北美北极地区的狗遗骸进行详细的时空分析，(2)利用线粒体DNA(MtDNA)和Y染色体分析史前、接触时期和现代北极狗的遗传史，以及(3)促进关于北方土著人民迁徙和文化互动的人类学和考古学讨论。

Given the importance of dogs to northern culture and their intertwined relationship to humans, this research project is designed to address questions related to the timing and spread of dogs from Asia to Alaska and Canada/Greenland and the development of local breeds. Using modern genetic methods to extract DNA from tooth and bone remains from well dated archaeological contexts in combination with radiocarbon-dating and analysis of recent samples, the PIs propose to (1) Provide a detailed temporal-spatial analysis of dog remains across the North American Arctic, (2) analyze the genetic history of prehistoric, contact period, and modern Arctic dogs using mitochondrial DNA (mtDNA) and the Y chromosome, and (3) contribute to anthropological and archaeological discussions concerning the movements and cultural interactions of indigenous peoples across the north.
