Was This 18,000-Year-Old Puppy Frozen in Siberian Permafrost the Ancestor of Wolves, Dogs or Both? DNA tests on the well-preserved remains can’t determine whether the little canine was wild or domestic.

Meet Dogor, an 18,000-year-old pup unearthed in Siberian permafrost whose name means “friend” in the Yakut language. The remains of the prehistoric pup are puzzling researchers because genetic testing shows it’s not a wolf or a dog, meaning it could be an elusive ancestor of both.

Locals found the remains in the summer of 2018 in a frozen lump of ground near the Indigirka River, according to the North-Eastern Federal University in Yakutsk. Parts of the animal are incredibly well-preserved, including its head, nose, whiskers, eyelashes and mouth, revealing that it still had its milk teeth when it died. Researchers suggest the animal was just two months old when it passed, though they do not know the cause of death.

The pup is so well-preserved that researchers at the Centre for Palaeogenetics in Sweden were able to sequence the animal’s DNA using a piece of rib bone. The results found that Dogor was male, but even after two rounds of analysis the team could not determine whether he was a dog or a wolf.

“It’s normally relatively easy to tell the difference between the two,” David Stanton, a Centre for Palaeogenetics research fellow, tells Amy Woodyatt at CNN. “We have a lot of data from it already, and with that amount of data, you’d expect to tell if it was one or the other. The fact that we can’t might suggest that it’s from a population that was ancestral to both—to dogs and wolves.”
