New analyses of ancient dog genomes, published in Nature, push the origins of close human–dog companionship back to at least 15,800 years ago—about 5,000 years earlier than previously believed. Researchers sequenced genomes from five sites from Britain to Turkey and found striking genetic similarity among hunter‑gatherer dogs. Archaeological evidence like feeding and careful burials suggests these animals were companions, and their ancestry persists in modern European dogs.

New genetic analyses reveal that close companionship between humans and dogs stretches back at least 15,800 years—about 5,000 years earlier than previous estimates. Recent studies published in Nature and reported by The New York Times sequenced ancient canine genomes from sites across Europe and Western Asia and show that hunter‑gatherer dogs were remarkably similar genetically despite belonging to very different human groups.
What the Research Found
International teams recovered and sequenced DNA from canine remains at five archaeological sites spanning present‑day Britain to Turkey. The oldest complete genome in the analysis dates to roughly 15,800 years ago from a site in Turkey; another key specimen from a British cave is about 14,300 years old. Researchers used these complete genomes to help interpret fragmentary genetic data from other locations, clarifying previously puzzling remains from Germany, Italy and Switzerland.
“The people are so different, but the dogs are very much the same,” said Greger Larson of the University of Oxford to the NYT, reflecting how consistent the canine genomes were across wide regions.
Behavioral and Archaeological Clues
Archaeological evidence at several sites suggests these Paleolithic dogs lived closely with people: some were provisioned with food, and a number were buried with care—behaviors consistent with companionate relationships rather than purely working or scavenging animals. William Marsh of the Natural History Museum told the NYT that such finds point to "very close interaction." While the precise roles of these early dogs remain unclear, the genetic and burial evidence together indicate they were integrated into human social life.
Legacy and Mixing With Farmer Dogs
When early farming populations moved into Europe about 9,000 years ago, their dogs mixed with these hunter‑gatherer lineages. Modern European dogs still retain a significant share of that ancient ancestry, meaning today's pet companions carry genetic traces of some of the earliest known human–dog relationships.
Open Questions
Scientists still do not know exactly where or how the initial bond began—whether domestication occurred repeatedly in multiple places or emerged through prolonged coexistence and selection. The new genomes, however, shift the timeline and strengthen the view that close human–dog relationships predate agriculture.
