And although there have been multiple admixture episodes, their Arctic ancestry component survives in the modern Samoyed breed,” says LMU palaeogeneticist Laurant Frantz, a co-author on the paper. The results indicate that the earliest introduction of new material appeared at least 2,000 years ago. We then analysed these genomes alongside those of publicly available genomes of ancient and modern dogs. “We wanted to gain insight to how modern dog breeds were formed, so in order to understand their development, we sequenced 20 Siberian and Eurasian Steppe dogs ranging in age from 11,000 years to just 60 years of age. And surprisingly, that much of the ancient dog DNA has actually survived in modern dogs. With the new study, the researchers show that the introduction of new genetic material in the ancient Siberian dog happened at least 2,000 years ago. Managing these large groups of reindeer likely required herding dogs, as seen today in Northwest Siberia. That includes the introduction of iron working, and later the beginning of the use of reindeer for transportation and the rise of reindeer pastoralism, the latter meaning reindeer were kept in large herds by human groups. Some introductions of new genetic material in the dogs coincide with periods of major transformations within the Northwest Siberian societies beginning at least 2,000 years ago. So there definitely were interactions between populations in these areas of Siberia.” We do not see that with dogs, which indicates that dogs were traded rather than moving with people. “At the same time, it looks like the human populations were more or less genetically isolated and did not mix with outside populations. Dogs were vital to the way society was running, so it also tells the story of why they were domesticated in the first place,” explains postdoc at GLOBE Institute Tatiana Feuerborn, lead author the study. Possibly because of new human activities, and we believe the dogs could have been used and traded for hunting, herding or sledding. “By creating genetic records of the ancient dogs alongside other archaeological findings, we were able to see a movement of dogs, potentially as goods that have been traded like a commodity. ![]()
