Scientists pulled DNA from the jaw of an ancient puppy that died about 15,800 years ago and reset the timeline for when dogs entered their relationship with humans.
The bones came from a rock shelter in Pınarbaşı, in what is now Turkey. Archaeologist Douglas Baird led the excavation years earlier and kept the small canine remains because their size and location beside human activity stood out from typical wolves.
Years later, researchers returned to those bones and used modern tools to extract both nuclear and mitochondrial DNA, rebuilding complete genomes. William Marsh and Lachie Scarsbrook led the genetic work, comparing the sequences to more than 1,000 modern and ancient dog and wolf genomes. The results separated early dogs from wolves with clarity. The Pınarbaşı puppy carried markers linked to domestication that didn’t appear in wild wolves from the same period.
"We putatively predict that dog and wolf populations diverged a lot earlier, likely before the last glacial maximum (of the Ice Age), so before 24,000 years ago. Although saying that, there is still a great degree of uncertainty," Marsh said.
The dog, descended from an ancient wolf population separate from modern wolves, was the first animal domesticated by people, with animals such as goats, sheep, cattle and cats coming later.
"Dogs have been by our side as humans underwent major lifestyle transitions and complex societies emerged," said geneticist Anders Bergström of the University of East Anglia in England, lead author of the other study, opens new tab.
"I think it's also interesting that, unlike most other domesticated animals, dogs do not always have very clearly defined roles or purposes for humans. Perhaps their primary role is often just to provide companionship," Bergström said.
The team paired DNA with chemical clues. Isotope analysis suggested that people at the site fed the pups fish from nearby wetlands, the same food they ate.
Some dogs were buried with care, a detail that points to more than tolerance and shows a shared life. Greger Larson helped lead the project and highlighted how quickly these dogs spread across Eurasia. A jawbone from Gough’s Cave in southwest England, dated to about 14,300 years ago, shares nearly identical ancestry with the Turkish puppy, even though the sites sit thousands of miles apart.
Another research effort strengthened the picture. Anders Bergström and Pontus Skoglund examined around 200 ancient canid samples, confirming early European dogs, including a 14,200-year-old specimen from Kesslerloch Cave in Switzerland. That dog already showed genetic ties to modern breeds such as boxers and salukis, rather than Arctic dogs like huskies.
Geneticists are pushing back the timeline of when people first domesticated dogs in Europe. Using the DNA from over 200 ancient dogs, geneticists found that we domesticated our best friends over 14,000 years ago. The dogs living in pre-agricultural Europe also substantially contributed to the genetics of those that would live after agriculture’s rise and up to the present. The findings are detailed in a study published today in the journal Nature.
“Dogs were the only domesticated animal to predate farming, so their evolution can help us understand how a big shift in lifestyle shaped our own history,” Pontus Skoglund, a study co-author and geneticist at the Francis Crick Institute, said in a statement.
The method behind the discovery rests on three steps. Scientists first dated the bones with radiocarbon. They then pulled DNA from tiny fragments inside teeth and jaws, reconstructing entire genomes. Finally, they used models to measure how far those sequences had drifted from wolf baselines. Bones alone couldn’t settle the question because early dogs and wolves look too similar, but the genomes provided the answer.
The timing matters. These dogs lived long before farms or villages appeared, when humans still moved as hunter-gatherers across cold landscapes. Yet they made room for dogs.
The new work supports the idea that all dogs came from one place, possibly somewhere in Asia, with additional interbreeding of early dogs and wolves, Adam Boyko, a geneticist at Cornell University who wasn’t involved in the new research, to Science News’ Tom Metcalfe. “Of course, we can’t rule out that some early fossils classified as wolves were actually tame and effectively dogs,” he adds. “But from the standpoint of modern dogs, it seems they all share a single domestication origin.”
Still, the researchers don’t know what roles the dogs played in hunter-gatherer populations 14,000 years ago, Laurent Frantz, a paleogeneticist at Ludwig Maximilian University of Munich in Germany who worked on both studies, tells the Times. It’s possible that they performed different jobs within each unique human society.
Some of the biggest mysteries around dogs remain to be uncovered. Scientists still don’t know where dogs come from, or who first domesticated them.
Early dogs likely helped track game, alert camps to danger, and share warmth. Their rapid spread suggests they offered a clear advantage that other groups wanted.
The story carries a quiet weight. A young female puppy left a trace in a shelter during the Ice Age. Thousands of years later, scientists read her DNA and found evidence of partnership.
Dogs didn’t wait for a settled life. They were already there, moving with people, sharing food, and earning their place beside the fire.
