Dogs have been essential to life in the Siberian Arctic for over 9,500 y, and this tight link between people and dogs continues in Siberian communities. Although Arctic Siberian groups such as the Nenets received limited gene flow from neighboring groups, archaeological evidence suggests that metallurgy and new subsistence strategies emerged in Northwest Siberia around 2,000 y ago. It is unclear if the Siberian Arctic dog population was as continuous as the people of the region or if instead admixture occurred, possibly in relation to the influx of material culture from other parts of Eurasia.

- Dire wolves were common large carnivores in Pleistocene America, but their evolution and extinction are not well understood.
- Researchers sequenced five genomes from dire wolf sub-fossils dating back 13,000 to over 50,000 years to study their evolutionary history.
- Findings reveal that dire wolves split from living canids about 5.7 million years ago, evolved in isolation without hybridizing with North American grey wolves or coyotes, and likely originated in the New World, contrasting with the Eurasian ancestry of grey wolves and coyotes.
