Mouflon the "Systema Naturæ", Linnaeus and Gmelin treated the mouflon and argali as one species. Von Schreiber used the combination "Ovis aries musimon" as early as 1782. In 1792, Robert Kerr listed the "Corsican argali" as a separate variety of argali ("Ovis Ammon europaea"), writing I have introduced this variety on the authority of Mr Pennant, who distinguishes between the Argali of Corsica and the Siberian, though the difference seems chiefly in colour ; one specimen brought from that island by the famous Paoli, differed from the above in colour, having a large white spot on the front of the neck,
Wild horse taxonomists considered domesticated and wild horse two subspecies of the same species, the valid scientific name was "Equus caballus" Linnaeus 1758, with the subspecies labeled "E. c. caballus" (domesticated horse), "E. c. ferus" Boddaert, 1785 (tarpan) and "E. c. przewalskii" Poliakov, 1881 (Przewalski's horse). However, in 2003, the International Commission on Zoological Nomenclature decided that the scientific names of the wild species have priority over the scientific names of domesticated species, therefore mandating the use of "Equus ferus" for the horse, independent of the position of the domesticated horse. Przewalski's horse occupied the eastern Eurasian Steppes, perhaps from the Urals
