Zebra history
Close relatives of the horse persist in the wild today in several parts of the Old World. Taxonomic interpretations vary, but most experts place them all in the genus Equus. The handsome striped equids of Africa fall into three distinct species: Grevy's zebra (Equus grevyi), the plains or Burchell's zebra (Equus burchelli =Equus quagga), and the mountain zebra (Equus zebra). Of these, the Grevy's zebra is most distinct. Taxonomically it is placed in the subgenus Dolichohippus, whereas the plains and mountain zebras are placed in the subgenus Hippotigris. The continued survival of most of these fascinating and spectacular species is threatened. Despite the establishment of sanctuaries, many populations are faced with diminishing ranges and decreasing numbers.
