Unique Sled Dogs Helped the Inuit Thrive in the North American Arctic

Inuit sled dogs have changed little since people migrated with them to the North American Arctic across the Bering Strait from Siberia, according to UC Davis researchers and colleagues who have examined DNA from the dogs from that time span. The legacy of these Inuit dogs survives today in Arctic sled dogs, making them one of the last remaining descendant populations of indigenous, pre-European dog lineages in the Americas.
