Summary
This Nature study uses genome-wide data from 216 ancient canid remains (mostly pre-Neolithic Europe) to resolve early dog versus wolf identities and to track dog ancestry through the Upper Palaeolithic, Mesolithic and Neolithic in Europe.
Key technical advance: the team designed an in-solution capture targeting ~486k SNPs to recover useful nuclear data from highly degraded samples, enabling dog/wolf calls for ~141 specimens and deep genomes for several individuals.
Major findings:
– A dog from Kesslerloch (Switzerland) dated to 14.2 ka is confirmed by genome-wide data as an Upper Palaeolithic dog, extending the time depth of diagnosable dog lineages.
– Most verified early European dogs derive predominantly from an eastern Eurasian (Siberian-like) wolf progenitor; a substantial western (Southwest Asian) wolf contribution is not required to explain pre-Neolithic European dog ancestry.
– The Kesslerloch dog (and an 11.4 ka Anatolian dog from Boncuklu) show a somewhat divergent ancestry profile, hinting at complex early structure and contacts between Europe and Southwest Asia.
– The Neolithic brought measurable Southwest Asian dog ancestry into Europe, but the replacement was partial and not as massive as in humans — Mesolithic dog lineages contributed substantially to Neolithic dog populations and to modern European dogs.
– Dogs already showed reduced genetic diversity by the Upper Palaeolithic, supporting an early diversity loss during domestication.
Key Points
- Genome-wide capture on ancient canid remains allowed reliable dog vs wolf calls for many pre-Neolithic samples.
- A 14.2 ka dog from Kesslerloch is confirmed as a member of the domestic dog lineage, pushing back detectable dog population structure to at least 14.2 ka.
- Pre-Neolithic European dogs mainly trace ancestry to an eastern Eurasian (Siberian-like) wolf source; no substantial western wolf contribution is required for these early European dogs.
- Some early individuals (Kesslerloch, Boncuklu) show divergent profiles linking Europe and Southwest Asia, indicating complex early connectivity.
- The Neolithic introduced Southwest Asian dog ancestry into Europe, but the effect was smaller than in humans — local Mesolithic dogs persisted and contributed significantly to later dog populations.
- Dogs had already lost a large fraction of genetic diversity by the Upper Palaeolithic, suggesting the diversity reduction occurred early in domestication.
Content summary
The authors sampled 216 canid remains from across Europe and adjacent regions, focusing on pre-Neolithic contexts. Because endogenous DNA was often very low, they developed a targeted SNP capture (486,547 variants) to enrich nuclear data. Capture increased usable endogenous content by 10–100× for many remains.
Using outgroup f3 tests and other population-genetic tools (PCA, ADMIXTURE, qpAdm, f4-statistics), they classified remains as dog or wolf and modelled ancestry sources. They confirmed a 14.2 ka dog at Kesslerloch and found Mesolithic dog populations across Scandinavia and Denmark. Most pre-Neolithic European dogs fit a model deriving from an eastern (Zhokhov-like) progenitor; evidence for the previously posited western (Southwest Asian) wolf contributor appears to emerge later and varies by region.
Modelling shows the Neolithic introduced Southwest Asian dog ancestry into many European dog populations (proportions varying by region), but Mesolithic lineages remained a major contributor. Heterozygosity analyses indicate low dog diversity was already present in Upper Palaeolithic and Mesolithic dogs.
Context and relevance
This paper tackles core questions about where and how dogs emerged: it provides the strongest genome-wide evidence so far that dogs present in Upper Palaeolithic Europe belonged to the same global domestic dog lineage and had deep population structure by 14.2 ka. The results narrow scenarios for domestication (favouring contributions from eastern wolf-like populations) and show Neolithic farming spread affected dog ancestry, but far less wholesale than in people.
Why should I read this?
Quick and dirty: if you care who our first four-legged buddies were and how they moved with (or ahead of) humans, this paper saves you hours of dense methods. It confirms a bona fide 14.2 ka dog, shows early dogs mostly carry eastern-derived ancestry, and explains that farmers didn’t wipe out local dog populations — they mixed. Big for archaeogenetics and anyone curious about dog origins.
Author style
Punchy: the study is a major step forward — genome-scale confirmation of dogs that far back matters. If you work on domestication, palaeogenomics or human–animal history, read the full paper for the models and regional Neolithic estimates; the summary here won’t replace their qpAdm tables and extended figures.
