>This article discusses ungulate mammals. For other meanings of horse, see Horse (disambiguation). The Horse (Equus caballus) is a sizeable ungulate mammal, one of the seven modern species of the genus Equus. It has long played an important role in transport, whether ridden or used for pulling vehicles. They are also used for food. Though horses may have been domesticated in one isolated locale in 4500 BC, the unequivocal date of (1) domestication and (2) use as a means of transport dates to no earlier than circa 2000 BC, evidenced by the Sintashta chariot burials (see Domestication of the horse).
