The Wolf Comes to the Fire

~23,000 years ago (debated)

Palaeolithic · Upper Palaeolithic · Last glacial · Last Glacial Maximum

The first domestic animal was not food but a companion: the dog, drawn from grey wolves somewhere in eastern Eurasia, plausibly in Siberia around 23,000 years ago while people and wolves wintered through the glacial maximum. Ancient genomes show dogs already travelling with the first people into the Americas, and modern dogs carrying ancestry from two distinct wolf sources, eastern and southwestern.

Why it matters

Before any field was sown, our species had already reshaped another animal's evolution, or been adopted by it: which partner domesticated which remains a fair question. Dogs guarded camps, hauled, hunted and warmed sleepers through the coldest millennia of the ice age, and they entered every continent at our side. The partnership is older than agriculture, older than pottery, older than any village.

Dating & uncertaintyDisputed

No consensus date exists. Comparing dog and human population histories suggests domestication in Siberia by about 23,000 years ago, during the glacial maximum; ancient wolf genomes show dogs closest to eastern Eurasian wolves, with a second, southwestern contribution, read either as a separate domestication or later mixing. Claimed Palaeolithic dogs up to 40,000 years old, and estimates as recent as 14,000, keep the window wide open.
