Taxonomy and evolution
Zebras were the second species to diverge from the earliest proto-horses, after the asses, around 4 million years ago. The Grevy's zebra is believed to have been the first zebra species to emerge. Fossils of an ancient equid were discovered in the Hagerman Fossil Beds National Monument in Hagerman, Idaho. It was named the Hagerman horse with a scientific name of Equus simplicidens. It is believed to have been similar to the Grevy's zebra. The animals had stocky zebra-like bodies and short, narrow, donkey-like skulls.[1] The Grevy's zebra also has a donkey-like skull. The Hagerman horse is also called the American zebra or Hagerman zebra.
There are three extant species, as well as several subspecies. Zebra populations vary a great deal, and the relationships between and the taxonomic status of several of the subspecies are well known.
The Plains Zebra (Equus quagga, formerly Equus burchelli) is the most common, and has or had about twelve subspecies distributed across much of southern and eastern Africa. It, or particular subspecies of it, have also been known as the Common Zebra, the Dauw, Burchell's Zebra (actually the subspecies Equus quagga burchelli), Chapman's Zebra, Wahlberg's Zebra, Selous' Zebra, Grant's Zebra, Boehm's Zebra and the Quagga (another extinct subspecies, Equus quagga quagga).
The Mountain Zebra (Equus zebra) of southwest Africa tends to have a sleek coat with a white belly and narrower stripes than the Plains Zebra. It has two subspecies and is classified as endangered.
Grevy's Zebra (Equus grevyi) is the largest type, with a long, narrow head making it appear rather mule-like. It is an inhabitant of the semi-arid grasslands of Ethiopia and northern Kenya. The Grevy's Zebra is one of the rarest species of zebra around today, and is classified as endangered.
