Bovines (subfamily Bovinae) comprise a diverse group of 10 genera of medium to large-sized ungulates, including cattle, bison, African buffalo, water buffalos, and the four-horned and spiral-horned antelopes. The members of this group of bovids are classified into loose tribes rather than formal subgroups, as the evolutionary relationships within the groups are still uncertain. General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur.

Caninae, whose members are known as canines (/keɪnaɪnz/),[6]: 182  is the only living subfamily within Canidae, alongside the extinct Borophaginae and Hesperocyoninae.[7][1] They first appeared in North America, during the Oligocene around 35 million years ago, subsequently spreading to Asia and elsewhere in the Old World at the end of the Miocene,[6]: 122  some 7 million to 8 million years ago.[7]
