Genetic study links aurochs extinction to multiple environmental and human stressors

Aurochs, the ancestors of modern cattle, faced a prolonged decline culminating in extinction 8,000 years after human activity began impacting their populations. New research from Lund University identifies a population bottleneck during their migration to Scandinavia, followed by habitat loss due to forest expansion and the isolation caused by rising sea levels flooding land bridges.

Genetic analysis reveals Scandinavian aurochs maintained contact with European populations until 8,000 years ago. Intense hunting combined with fragmented habitats ultimately doomed the species. This study provides crucial insight into how species vulnerability, ecosystem transformation, and human activity shaped the demise of these ancient animals in northern Europe.
