The evolutionary history of dogs in the Americas
- Abstract:
- Dogs were present in the Americas before the arrival of European colonists, but the origin and fate of these precontact dogs are largely unknown.We sequenced 71 mitochondrial and 7 nuclear genomes fromancient North American and Siberian dogs from time frames spanning ~9000 years. Our analysis indicates that American dogs were not derived from North American wolves. Instead, American dogs form a monophyletic lineage that likely originated in Siberia and dispersed into the Americas alongside people. After the arrival of Europeans, native American dogs almost completely disappeared, leaving a minimal genetic legacy in modern dog populations.The closest detectable extant lineage to precontact American dogs is the canine transmissible venereal tumor, a contagious cancer clone derived froman individual dog that lived up to 8000 years ago.
