Few species of ass exist in the wild. The African wild ass, "Equus africanus", has two subspecies, the Somali wild ass, "Equus africanus somaliensis", and the Nubian wild ass, "Equus africanus africanus", the principal ancestor of the domestic donkey. Both are critically endangered. Extinct species include the European ass, "Equus hydruntinus", which became extinct during the Neolithic, and the North African wild ass, "Equus africanus atlanticus", which became extinct in Roman times. There are five subspecies
Australopithecus africanus Little Foot is currently classified as (lumped into) "Australopithecus africanus"; Clarke suggests that Little Foot doesn't belong to either species "afarensis" or "africanus," but to a unique "Australopithecus" species found at Makapansgat and Sterkfontein (and named "Australopithecus prometheus" by Raymond Dart). Analysis made in 2015 by a new radioisotopic technique dated the Little Foot specimen to about 3.7 mya. "A. africanus" was similar in many traits to "A. afarensis", a bipedal hominin with arms slightly longer than the legs (a physical trait also found in chimpanzees). It has slightly human-like, advanced cranial features (seen in the crania of Mrs. Ples
