The project stems from a plan to reintroduce a version of the quagga, an extinct species of zebra, into the population by selectively breeding in South Africa and then reintroducing them into the original quagga plain.
Apparently, in 1987 Reinhold Rau discovered that there was a very close relationship between quaggas and extant plains zebras. However, in breeding back, this quagga-like zebras will only resemble the quagga in appearance but they will be genetically different, as there is no known way to recover DNA.
The quagga was a plains zebra that was believed to extinct in the late 19th century. However, studies have shown that that a sub-species of this zebra exists.
The zebra looks different to others in that the head and the front part of the body appear striped white and brown and then fades into the color brown the farther you move toward the back of the horse. When they existed, they were found mostly in the Karoo of Cape Province and the Orange Free State of South Africa.
