Dogs Were Domesticated Once from a Lost Population of Wolves

Dogs were domesticated once from a lost population of wolves:
Genomics researcher Anders Bergstrom and his colleagues recently sequenced the genomes of 27 dogs from archaeological sites scattered around Europe and Asia, ranging from 4,000 to 11,000 years old. Those genomes, along with those of modern dogs and wolves, show how dogs have moved around the world with people since their domestication.
All the dogs in the study descended from the same common ancestor, but that original dog population split into at least five branches as it expanded in different directions. As groups of people split apart, migrated, and met other groups, they brought their dogs along. Dog DNA suggests that their population history mirrors the story of human populations, for the most part.
[...] We still don't know exactly when or where dog domestication first happened; it already had a pretty complex history by 11,000 years ago. But it looks like it only happened once. The ancient genomes suggest that dogs all share a common ancestor, which they don't share with modern wolves. According to Bergstrom and his colleagues, that probably means that dogs all descend from one group of wolves, and that group is now extinct.
