For many years, scientists knew that humans and dogs had an ancient connection, but they could not say exactly when true domestic dogs first appeared. That picture changed in March 2026, when two studies in Nature reported the oldest dog genomes ever sequenced. Researchers analyzed ancient canid remains from sites including Gough’s Cave in Britain and Pınarbaşı in Türkiye, and identified dogs dating to roughly 14,000–16,000 years ago. This pushes confirmed genetic evidence for domestic dogs back by more than 5,000 years. (nature.com)

One of the most interesting findings is that dogs were already living across western Eurasia before farming began. In other words, they were companions of hunter-gatherers, not just of later farming societies. At Pınarbaşı, scientists studied chemical signs in bones and found that dogs ate a fish-rich diet very similar to the humans there. Because dogs were unlikely to catch so much fish by themselves, this strongly suggests that people were feeding them. The studies also point to a close social bond: at Bonn-Oberkassel in Germany, a dog-like canid from about 14,300 years ago seems to have survived only because humans cared for it over a long period.

The DNA also shows that early dogs were not all the same. By around 15,000 years ago, important dog lineages had already begun to split, and dogs with different ancestries existed from western Europe to Siberia. Some of that ancient history still survives in modern animals: one of the new studies suggests that today’s European dogs probably inherited a substantial part of their ancestry from dogs that lived in Europe before agriculture. Still, one big mystery remains. Earlier wolf-genome research suggests that the first dog ancestors were genetically closer to ancient wolves from Siberia or eastern Eurasia than to known European wolves, so the exact birthplace of dogs is still unknown. Even so, the new evidence makes one thing clear: the human-dog story began deep in the Ice Age, when people and canines were already learning to live together. (nature.com)
