But only one of those animals would go on to replace almost all of the world’s wild horses, and that was the one from the west of the Urals (Equus caballus). The last descendants of the Botai’s line are the Przewalski’s horses (Equus przewalskii) that still roam the Mongolian steppe and were once thought to be wild, but are in fact feral (having once been domesticated, that is, they have reverted to the wild state).
