NEW YORK — For years, scientists have been dogged by this evolution question: Just where did man’s best friend first appear?
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.
