- A Nature study led by University of York researchers found the earliest genetic evidence of domestic dogs in remains from Gough's Cave (UK) and Pınarbaşı (Türkiye), confirming dogs lived alongside humans at least 14,000 years ago and pushing back confirmed domestication evidence by more than 5,000 years.
- A dog jawbone from Gough's Cave, dating to approximately 15,000 years ago, is now the earliest known domesticated dog in the UK, per the research team.
- Scientists reconstructed whole genomes from remains more than 10,000 years old and compared them with over 1,000 modern and ancient canids, confirming dogs were already widespread across Europe and western Asia by at least 14,000 years ago.
- Isotope analysis at Pınarbaşı revealed Ice Age dogs consumed fish-rich diets closely matching those of local humans, strongly suggesting people were actively feeding them rather than dogs foraging independently.
- Genetic analysis showed these early dogs were more closely related to ancestors of modern European and Middle Eastern breeds than to Arctic dogs, indicating major dog lineages were already established around 15,000 years ago, according to LMU Munich's Dr. Lachie Scarsbrook.
- The study identified dogs among diverse hunter-gatherer groups, including Epigravettian and Magdalenian communities across sites in the UK, Germany, Italy, Switzerland, and Türkiye toward the end of the last Ice Age.
- The findings raise the possibility that dogs were domesticated more than 10,000 years before any other animals or plants, making them humanity's earliest domesticated species by a wide margin.
Why it matters: If dogs were domesticated more than 10,000 years before any other animal or plant, as the researchers suggest, it means the human-canine partnership predates farming entirely — meaning the first animal humans tamed wasn't livestock raised for food, but a companion species integrated into mobile Ice Age hunter-gatherer communities. That rewrites the origin story of animal domestication and suggests the behavioral and emotional bond with dogs was a Paleolithic innovation, not a Neolithic one.
