Archeological finds show that people in the Arctic regions of Northwestern Siberia had already established long-range trading links with Eurasian populations some 2000 years ago. The initiation of trading relationships was one of a series of significant social changes that took place during this period. Moreover, these changes even had an impact on the genomes of Siberian dogs, as an international team of researchers led by LMU palaeogeneticist Laurent Frantz has now demonstrated. Based on extensive genetic analyses, the team concludes that dogs were imported into the Siberian Arctic, and that this process ultimately led to the establishment of Siberian breeds such as the samoyed.
