The only one true wild (never domesticated) equine in the world today is the equus ferus Przewalski horse, also known by its indigenous name Takhi (Mongolian), Je-ma/Yěmǎ (Chinese), Asian wild horse or Mongolian wild horse. Although the genetic base relies only on 27 specimen that were kept in Zoos, the Takhi nowadays repopulates the steppes in Mongolia, China and Kazakhstan. Modern studies show that the Takhi might be descendants of the Botai horses returned to the wild 5000 years ago.
With great success the horses got reintroduced into the wild and many more rewildering projects continue a great work. Also projects in Europe start to prepare the horses, by introducing them into vaster areas and grazing projects.
