This means that the proper scientific name for the donkey is "Equus africanus asinus" when it is considered a subspecies, and "Equus asinus" when it is
Australopithecus africanus of the Witwatersrand in Johannesburg, South Africa, became interested in fossils found at a limestone quarry at Taung near Kimberley, South Africa in 1924. The most promising of these was a skull of an odd ape-like creature presenting human traits at the eye orbits, teeth, and, most importantly, the hole at the base of the skull over the spinal column (the foramen magnum); its placement indicated a human-like upright posture and implied a high probability that this hominid-to-hominin primate had achieved bipedal, as opposed to quadrupedal locomotion. Dart assigned the specimen the name "Australopithecus africanus" ("southern ape of Africa"); it
