Wild horse stock from which domesticated horses are descended. The horse family Equidae and the genus "Equus" evolved in North America, before the species moved into the Eastern Hemisphere. Studies using ancient DNA, as well as DNA of recent individuals, show the presence of two closely related horse species in North America, the wild horse and "Haringtonhippus francisci", the "New World stilt-legged horse"; the latter has been taxonomically assigned to various names. Currently, three subspecies that lived during recorded human history are recognized. One subspecies is the widespread domestic horse ("Equus ferus caballus"), as well as two wild subspecies: the recently extinct
