Bovina is a subtribe of the Bovini tribe that generally includes the two living genera, Bison and Bos.[2] However, this dichotomy has been challenged recently by molecular work that suggests that Bison should be regarded as a subgenus of Bos.[3][4][5][6] Wild bovinans can be found naturally in North America and Eurasia (although domestic and feral populations have been introduced worldwide).[7]
