The Tarpan, Equus ferus ferus, was the Eurasian wild horse. The last Russian specimen of this species died in a Moscow zoo in 1875.
Polish farmers often crossed the tarpan with their domestic horses. The result was a small horse breed, the Konik. Such animals, as the Konik, and also the Sorraia Horse preserved in Portugal, are now being used to breed back the Tarpan, and to fill in the niche that was left vacant by their extinction in the wild. The Hucul pony living in the Carpathian mountains is arguably the most direct descendant of the Tarpan.
It is now thought that the domesticated horse, named Equus caballus by Linnaeus in 1758, is descended from the Tarpan; indeed, many taxonomists consider them to belong to the same species. By a strict application of the rules of the International Code of Zoological Nomenclature, the Tarpan ought to be named E. caballus, or if considered a subspecies, E. caballus ferus. However, biologists have generally ignored the letter of the rule and used E. ferus for the Tarpan to avoid confusion with its domesticated cousins.
In 2003, the International Commission on Zoological Nomenclature "conserved the usage of 17 specific names based on wild species, which are pre-dated by or contemporary with those based on domestic forms", confirming E. ferus for the Tarpan. Taxonomists who consider the domestic horse a subspecies of the wild Tarpan should use Equus ferus caballus; the name Equus caballus remains available for the domestic horse where it is considered to be a separate species.
