From my understanding, exactly how "wild" these horses are is mildly controversial, with some claiming that they have a non-trivial amount of domesticated horse ancestry. From Wikipedia: >Przewalski's horse was formally described as a novel species in 1881 by Ivan Semyonovich Polyakov. The taxonomic position of Przewalski's horse remains controversial, and no consensus exists about whether it is a full species (as Equus przewalskii); a subspecies of Equus ferus the wild horse (as Equus ferus przewalskii in trinomial nomenclature, along with two other subspecies, the domestic horse E. f. caballus, and the extinct tarpan E. f. ferus); or even a subpopulation of the domestic horse.[6][7][8] The American Society of Mammalogists considers the Przewalski's horse and the tarpan both to be subspecies of Equus ferus, and classifies the domestic horse as a separate species, Equus caballus.[9]
