The quagga was born some 200,000 years ago when a group of plains zebras wandered into the Great Karroo, a dried-out inland sea in southern Africa. Separated from all other zebras, this group evolved differently and eventually became a unique animal. Humans soon took note of the quagga, for example in cave drawings. This is a rubbing of one that dates from between A.D. 200 and 800.
