Competing clues confuse story of dog domestication
The ancient lineage of man’s best friend is kind of a tangled mess. But scientists made some progress this year in identifying dogs’ ancestors and in estimating the timeline of canine domestication.
Dogs may have descended from a now-extinct wolf species, Adam Freedman of Harvard and colleagues reported in June (SN: 7/13/13, p. 14). They date dog domestication to between 11,000 and 16,000 years ago, before the rise of agriculture.
