Any member of the zoological tribe Hominini (family Hominidae, order Primates), of which only one species exists todayHomo sapiens, or human beings. The term is used most often to refer to extinct members of the human lineage, some of which are now quite well known from fossil remains: Homo neanderthalensis (the Neanderthals), Homo erectus, Homo habilis, and various species of Australopithecus. In addition, many authorities place the genera Ardipithecus, Orrorin, and Kenyanthropus in Hominini. The primate group most closely related to Hominini today is Gorillini (the African apes), comprising the gorilla, the chimpanzee, and the bonobo. Gorillini and Hominini are part of the great ape family, Hominidae. Some characteristics that have distinguished hominins from other primates, living and extinct, are their erect posture, bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use and, in some cases, communication through language.
