According to a paper published in the latest issue of the proceedings of the National Academy of Sciences, Danish scientists have found that the DNA of ancient dog remains unearthed in Siberia shows that they hybridized with other dogs from Europe and the near east around 5000 BC, which means that Arctic residents traded with Europe and the Near East as early as 7000 years ago, 5000 years earlier than the previous view.
It is reported that the research team led by the archaeologist Tatiana feuerborn of the University of Copenhagen analyzed the DNA of the remains of 49 Siberian ancient dogs and found that some of them were mixed with other dog populations from the Eurasian prairie, the Near East and Europe.

These remains were found in 2016. They were unearthed in the dog cemetery of an archaeological site called ust polui in Salekhard, Russia's Arctic circle. A total of 115 dog remains were found.
The team believes that these Siberian ancient dogs were deliberately hybridized with dogs from other regions, so that people can sell mixed offspring at a high price.
Overall, this shows that these profound changes in Northwest Siberia are related to the import of material culture (including dogs) from neighbouring regions through the establishment of large-scale trade networks.
Dogs appeared in the Arctic about 9500 years ago, enabling those living in frozen wasteland to venture outside the isolated world.

The team analyzed the DNA of ancient dog remains from 9500 to 2000 years ago. The earliest remains were found near a series of non-native materials unearthed in Northwest Siberia.
Tatiana said she and her team wanted to know whether the remains of these dogs and other remains in Siberia could reveal the timeline of a different ancient trade network.
According to research, ancient Arctic dogs may have lived in a large area of Siberia from the Novosibirsk islands to Lake Baikal. However, over the past 7000 years, their purebred lineage has been changed by several dogs introduced from the Eurasian grasslands and Western Europe.
