The earliest known doglike fossils come from Europe. But DNA studies have implicated east Asia and the Middle East. Now a large DNA study is lining up with the fossils, suggesting dogs originated in Europe some 19,000 to 32,000 years ago.
Experts praised the new work but said it won’t end the debate.
Scientists generally agree that dogs emerged from wolves to become the first domesticated animal. Their wolf ancestors began to associate with people, maybe drawn by food in garbage dumps and carcasses left by human hunters. In the process they became tamer, and scientists believe people found them useful for things like hunting and guard duty. Over a very long time in this human environment, wolves gradually turned into the first dogs.
The latest attempt to figure out where this happened was published online Thursday by the journal Science.
