Equus (genus) Equus (genus) Equus is a genus of mammals in the family Equidae, which includes horses, donkeys, and zebras. Within Equidae, "Equus" is the only recognized extant genus, comprising seven living species. The term equine refers to any member of this genus, including horses. Like Equidae more broadly, "Equus" has numerous extinct species known only from fossils. The genus most likely originated in North America and spread quickly to the Old World. Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes (erect in most subspecies), and long tails. All species are herbivorous, and mostly grazers, with simpler
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
