When, where and how wolves were domesticated and eventually became dogs has always been disagreed upon by scientists. Now, new research suggests our best pals have a different origin story than once thought. Archaeologist and geneticist Greger Larson now believes—after extensive study—that dogs were domesticated not once, but twice. (It makes sense then, that the origin times and places were disputed.) Around the same time, Larson says dogs were domesticated in the East and the West (judging by bones found in both areas) and then, apparently, these dogs mated—thanks to their migrating owners—and became the pooches of today.
