Quote:How dogs became man’s best friend – twice over
Quote:It was widely believed dogs were tamed just once, with some experts claiming this happened in Europe and others favoring central Asia or China.
But a new story emerged when researchers used the inner ear bone from a 4,800-year-old dog unearthed in Ireland to sequence its full genome, and then compared it to both modern animals and DNA traces from 59 ancient dogs.
“Our data suggests that dogs were domesticated twice, on both sides of the Old World,” said Laurent Frantz, a geneticist at the University of Oxford, whose work was published in the journal Science.
