''Bos'' (from Latin ''bōs'': cow, ox, bull) is a genus of bovines, which includes, among others, wild and domestic cattle.

''Bos'' is often divided into four subgenera: ''Bos'', ''Bibos'', ''Novibos'', and ''Poephagus'', but including these last three divisions within the genus ''Bos'' without including ''Bison'' is believed to be paraphyletic by many workers on the classification of the genus since the 1980s. The genus as traditionally defined has five extant species, but this rises to eight when the domesticated varieties are counted as separate species, and ten when the closely related ''Bison'' is also included.Most but not all modern breeds of domesticated cattle (including taurine cattle and zebu) are believed to have originated from the extinct aurochs. Others like Bali cattle and gayal are thought to have originated from South and Southeast Asian ''Bos'' species Provided by Wikipedia
