UNDATED (AP) -- The question of where dogs first appeared has always been complex, and now a new study suggests it may have two answers.

Dogs arose from the domestication of wolves, and the new work suggests this happened twice, once in Asia and also in either Europe or the Near East.

In a paper released Thursday by the journal Science, scientists stressed that their conclusion is only a hypothesis, and that more work is needed to assess it.

The study drew on analysis of DNA samples from ancient and modern dogs, as well as archaeological records.

Dogs were the first domesticated animal, the only one to appear before people settled down to be farmers.
