The wild ancestor of domestic cattle

The aurochs was a large wild bovine. It became extinct after coexisting for thousands of years with people.

History and context

The aurochs roamed Europe, Asia and North Africa. Its large horns appear in Palaeolithic art and males could approach two metres in height and one tonne in weight.

Its end was surprisingly recent: in 1627 the last known female died in Jaktorów. A species painted by prehistoric artists survived into the Modern Age and disappeared after habitat loss and overexploitation.

Evidence and interpretation

The final date comes from historical records. Habitat loss and overexploitation explain its decline; it was not simply an oversized domestic bull.

Domestication did not close the frontier with the wild

Ancient DNA allows us to investigate a history that horns do not tell. A 2024 genomic study identifies the initial capture of a small number of aurochs from southwestern Asia and subsequent interbreeding, especially mediated by males, between cattle and wild populations as herds spread. Domestication was not an instantaneous and definitive separation. That exchange helps explain why cattle ancestry retains a complex geography, even though the aurochs disappeared as a recognisable wild population.
