Trinity researchers uncover genetic diversity in ancient European aurochs

New research from Trinity College Dublin reveals that European aurochs, the ancestors of modern cattle, had three distinct populations: Western European, Italian, and Balkan. This finding shows greater genetic diversity than previously recognized. The study analyzed 38 ancient genomes from aurochs bones across Europe and Siberia, dating back 50,000 years. It indicates that these populations diverged during the last ice age, with significant genetic loss due to human domestication. The research highlights how early cattle were influenced by wild aurochs, contributing to the genetic makeup of modern cattle. This work adds to the understanding of ancient species and their evolution.
