Summary

This Nature study uses new radiocarbon dates, nuclear genomes and mitochondrial data from Palaeolithic and Mesolithic canids (including specimens from Gough’s Cave, UK, and Pınarbaşı, Türkiye) to show that dogs were already widespread across western Eurasia in the Late Upper Palaeolithic (~18,500–14,000 years ago).

Nuclear-genome analyses identify multiple Palaeolithic individuals as true dogs (not wolves) and reveal a distinct mitochondrial subclade (C5) shared across sites in Britain, central Europe and Anatolia. Genomes indicate these Palaeolithic dogs belonged to the western Eurasian dog lineage; eastern–western dog divergence had already occurred by at least ~15,800 years ago. Isotope data and burial contexts show close human–dog associations, while limited local wolf admixture is detected mainly in Near Eastern dogs after the Palaeolithic. The study argues this early dog population spread across Europe likely alongside the expansion of Epigravettian-associated people and material culture, and that key ancestry components persisted into later periods and modern breeds.

Key Points

• Direct nuclear genomes confirm dogs were present in western Eurasia during the Late Upper Palaeolithic (examples: ~15,800 yr cal bp Pınarbaşı; ~14,300 yr cal bp Gough’s Cave).
• Multiple Palaeolithic specimens cluster in a distinct mitochondrial clade (C5), implying a widespread, genetically similar dog population across Britain, central Europe and Anatolia.
• Palaeolithic dogs belong to the western Eurasian dog lineage; the east–west dog split predates ~15,800 years ago.
• Dietary isotope and burial evidence indicate close life and ritual associations between humans and dogs in Palaeolithic contexts.
• Near Eastern wolves contributed measurable admixture to some Near Eastern and African dogs (Neolithic onward), but overall wolf introgression into European dogs remained minimal.
• The ancestry of this Palaeolithic dog population persisted through the Holocene and contributed to later European dog populations and modern breeds.

Context and Relevance

This work addresses a long-standing debate about when and where dogs first became distinct from wolves. By combining ancient nuclear genomes, mitogenomes, radiocarbon dating and isotope analysis across multiple sites, the paper provides robust evidence that dog-like, reproductively distinct populations were already established and widely distributed in western Eurasia during the Late Palaeolithic. The findings tie canine dispersal to human cultural movements (notably Epigravettian-related spreads) and show that dogs and humans sometimes had different population histories — a key insight for archaeogenetics, palaeoecology and studies of human–animal relationships.

Why should I read this?

Because if you care about when dogs became our companions (and how they spread with people), this paper is the real deal — genomes, dates and isotopes all lined up. It rewrites the timing and geography of early dog dispersal across western Eurasia and gives a clearer picture of how early people treated and moved with dogs. Short version: yes, dogs were already a thing across Europe and Anatolia in the Late Palaeolithic, and the evidence is tight.

Author style

Punchy: the authors combine multiple lines of biomolecular and archaeological evidence to deliver a decisive update on early dog history. Important — this isn’t a small tweak: it constrains when dog populations that are ancestral to many later European dogs became distinct and widespread.
