15,000-yr-old cave art unveils hybrid of cattle, bison
Ancient DNA research has unveiled that Ice Age artists recorded a previously unknown hybrid species of bison and cattle on cave walls over 15,000 years ago. Known by the researchers as the 'Higgs Bison', the species is estimated to have originated over 120,000 years ago through hybridisation of extinct Aurochs and Steppe bisons, eventually becoming ancestors of modern European bisons.
