The First Domestic Animal

~23,000 years ago (estimates 40,000 to 14,000)

Phanerozoic · Cenozoic · Quaternary · Pleistocene · Late Pleistocene

Wolves that tolerated people became dogs, thousands of years before any crop was sown or any other animal kept. Seventy-two ancient wolf genomes, spanning the last hundred thousand years, make eastern Eurasia their likelier birthplace, and show that dogs in the Near East and Africa draw as much as half their ancestry from a second, western source. Dogs then travelled with people into the Americas.

Why it matters

The first domestication was not of a food source but of a hunting partner, and it came while people everywhere still lived off wild plants and animals. Its raw material is also still alive: grey wolves came through the last Ice Age when many other large mammals did not. The before and the after can be compared directly, which is why the dog is one of the animals whose domestication we can follow most closely.

Dating & uncertaintyDisputed

Dog genomes, set against those of 72 ancient wolves, point to a domestication in eastern Eurasia, with a second ancestry in the Near East and Africa that is either a separate domestication or later mixing with local wolves. Dates from bones and from genomes have not converged: estimates run from 40,000 to 14,000 years ago.
