EASTERN INFLUENCE  Dogs may have been domesticated separately in East Asia and Europe, a new study suggests. Those separate dog groups got together when Eastern dogs moved west with humans and partially replaced dogs living in Europe. Those events happened thousands of years before breeds, such as Chinese shar-peis (left) and German shepherds (right), were created.

Dogs were domesticated at least twice, a new study suggests.

Genetic analyses of a 4,800-year-old Irish dog and 59 other ancient dogs suggest that canines and humans became pals in both Europe and East Asia long before the advent of farming, researchers report June 3 in Science. Later, dogs from East Asia accompanied their human companions to Europe, where their genetic legacy trumped that of dogs already living there, the team also concludes.
