A dog skull unearthed in a cave in the Altai Mountains of Siberia is believed to be 33,000 years old.

If so, it represents some of the oldest known evidence of dog domestication,  according to a recent study in the online journal PloS One.

The Siberian skull, along with equally ancient dog remains found in a cave in Belgium, indicate domestic dogs may have come from more than one ancestor, more than one area, and more than one era — contrary to popular scientific belief.

Researchers say the skull’s shortened snout — not as long and narrow as that of a wolf — is evidence the creature it came from was domesticated.

“Essentially, wolves have long thin snouts and their teeth are not crowded, and domestication results in this shortening of the snout and widening of the jaws and crowding of the teeth,” said Greg Hodgins, a researcher at the University of Arizona’s Accelerator Mass Spectrometry Laboratory and co-author of the study. “What’s interesting is that it doesn’t appear to be an ancestor of modern dogs.”

The Siberian skull predates the last great ice age, and Hodgins believes neither the Belgian nor the Siberian lineages survived the severe conditions.

Hodgins suspects even pre-ice age dogs were pets and helpers, as opposed to food sources.

“The dogs are not necessarily providing products or meat. They are probably providing protection, companionship and perhaps helping on the hunt. And it’s really interesting that this appears to have happened first out of all human relationships with animals.”
