African wild ass (Equus)" which diverged ~4.8 (3.2–6.5) million years ago. Different authors consider the African wild ass and the domesticated donkey one or two species; either view is technically legitimate, though the former is phylogenetically more accurate. The species name for the African wild ass is sometimes given as "asinus", from the domestic donkey, whose specific name is older and usually would have priority. But this usage is erroneous since the International Commission on Zoological Nomenclature has conserved the name "Equus africanus" in Opinion 2027. This was done to prevent the confusing situation of the phylogenetic ancestor being taxonomically included in its
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
