   Sammanfattning : All contemporary taurine cattle originated some 10,000 years ago when their wild ancestor, the aurochs, was domesticated in the Near East. Although the aurochs was widespread also in Europe, there is no evidence for a local domestication. The aurochs has been extinct since 1627 and therefore little is known about its biology. LÄS MER
