What the study found

A genetically homogeneous dog population was already widely distributed across Europe and Anatolia during the Late Upper Palaeolithic, by at least 14,300 years ago.

Why the authors say this matters

The authors suggest this means dogs were exchanged among genetically and culturally distinct western Eurasian Late Palaeolithic human populations, including the Magdalenian, Epigravettian, and Anatolian hunter-gatherers.

What the researchers tested

The researchers generated nuclear and mitochondrial genomes from canid remains from Pınarbaşı in Türkiye and Gough's Cave in the UK, and from dogs from two Mesolithic sites in Serbia, Padina and Vlasac. They compared these genomes to assess dog ancestry and distribution across time and regions.

What worked and what didn't

The analyses indicated a shared dog population across the regions sampled in the Late Upper Palaeolithic. The study also identified a major influx of eastern Eurasian dog ancestry during the Mesolithic, associated with eastern hunter-gatherer movement into Europe, which led to the ancestry pattern seen in European dogs today.

What to keep in mind

The abstract does not describe detailed limitations beyond the geographic and chronological scope of the sampled remains. The conclusions are based on the specific ancient genomes and sites named in the study.

Key points

  • Ancient dog genomes from Türkiye, the UK, and Serbia were analyzed.
  • A genetically homogeneous dog population was already widespread in Europe and Anatolia by at least 14,300 years ago.
  • The authors suggest dogs were exchanged among distinct western Eurasian hunter-gatherer populations.
  • A major influx of eastern Eurasian dog ancestry occurred during the Mesolithic.
  • This Mesolithic ancestry shift helped shape present-day European dog populations.
