World's Oldest Known Dogs Discovered in Anatolia, Pushing Back Domestication by 5,000 Years

Three puppies buried in a ritual pit above a human grave at a rockshelter in central Anatolia have been genetically confirmed as the oldest known domesticated dogs. Dating to approximately 15,800 years ago, the discovery pushes back the record by 5,000 years and confirms that dogs lived alongside humans thousands of years before the invention of agriculture.

A Discovery 20 Years in the Making

Professor Douglas Baird of the University of Liverpool excavated the Pınarbaşı rockshelter in Karaman Province, Turkey, over multiple seasons. In the summer of 2004, his team found three puppies deliberately placed in a pit directly above a human burial. But confirming whether the animals were dogs or wolves required genetic technology that took more than 20 years to develop.

An international team from 17 research institutes, including LMU Munich, the Francis Crick Institute, and Oxford University, analyzed 216 canid skeletal remains from sites across western Eurasia. Using a technique called hybridization capture, which enriches useful genetic signal by 10 to 100 times, the researchers determined that the Pınarbaşı puppy was a female with zero wolf ancestry in her nuclear genome.

The findings were published in two landmark papers in Nature in March 2026.

Dogs Ate What Humans Ate

Isotopic analysis of the puppies' bones revealed they had been eating fish, the same food that formed a major component of the human diet at Pınarbaşı. Professor Baird concluded: "The archaeology makes clear that these dogs were close companions of humans." He hypothesized they likely served as hunting assistants and guard animals, given the presence of dangerous predators including wolves and leopards in the region.

Why This Matters

Dogs were, by an enormous margin, the first domesticated organism of any kind. They preceded the domestication of sheep, goats, cattle, wheat, and every other plant and animal by at least 5,000 years. The deliberate burial of puppies above a human grave, the shared diet, and the rapid continental spread all point to a relationship that was not merely utilitarian but carried emotional and possibly spiritual dimensions.

Rapid Spread Across a Continent

One of the study's most remarkable findings is the genetic similarity between the Pınarbaşı dogs and a 14,300-year-old dog jawbone from Gough's Cave in England, despite the two sites being separated by more than 4,000 kilometers. This means that by approximately 14,000 years ago, a genetically homogeneous population of domesticated dogs had already spread from Anatolia to the British Isles.

The second Nature paper, led by Anders Bergström of the Francis Crick Institute, found that all early dogs share ancestry from an eastern wolf source, supporting the single-origin theory of dog domestication.
