Changes

Przewalski's horse became known to the West after its late-19th century discovery in western [[Mongolia]] by the Russian explorer N.M. Przhevalsky.  A rare animal even then, Preswalski's horse was declared extinct in the wild by the 1970's either through cross-breeding with feral domestic horses or through shooting to prevent grazing on farmland.  European and American zoos kept the species alive, however, and by the late 20th century many of them were sent to Mongolia where they were released into the wild.

The tarpan, the horse which decorated cave walls in western Europe, survived until about 1900 in herds which dwindled in size as a result of human encroachment.  Under the theory that crossbreeding with horses occured, the Munich Zoo carried out selective "back-breeding" of animals known to have tarpan genes, succeeding in producing a breed that at best is "tarpan-like" enough to be exibited in zoos as well as released to the wild in selected areas of Europe.  The new tarpan is generally grey in color, with a non-erect mane, unlike the cave wall images which are similar to Przewalski's horse.
