Humans are part of the order primates, under the family, Superfamily Hominoidea (apes and humans; informally “hominoids”), Family Hylobatidae (informally “hylobatids”), Family Hominidae (African apes and humans; informally “hominids”), Subfamily Homininae (chimpanzees and humans, “hominines”), Tribe Panini (chimpanzees and bonobos; informally “panins”), Tribe Hominini (informally “hominins,” replacing hominids), Subtribe Australopithecina (informally “australopiths”). Since Taieb's first explorations, the Afar has become the most important place on earth for the study of human origins and evolution. Its nonhuman members are restricted to rain forests in equatorial Africa, Sumatra and Borneo. The origins of Australopithecus have been a key research problem for the 75 years since Dart's initial discovery of this genus in South Africa. While wild chimpanzees have been classified as endangered since, 1990, captive chimpanzees have bred well in captivity and were not considered to be endangered, but instead, classified as ‘threatened’ (UFWS, 2013). In December 2010, the NIH commissioned a study by the Institute of Medicine (IOM) to assess the need for chimpanzees in biomedical and behavioral research.

Discovery of the relatively complete and well-preserved fossil specimen nicknamed “Lucy” by anthropologist Donald Johanson in 1974 first focused global attention here. Details of the classification are not universally agreed at present. Human belongs to the Animalia kingdom that comprises all animals. They were thought to be ruled by impulse.

There are very few places in Africa, let alone the rest of the world, where a dead organism has a good chance of becoming fossilized. Humans are further classified in the phylum, chordata, which includes the vertebrate animals. Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. The NIH accepted this IOM report and charged a NIH Council of Councils Working Group to propose advice on implementing the recommendations of the IOM report and to provide recommendations on the size and placement of NIH-owned chimpanzee populations. Because chimpanzees, bonobos, and humans are more closely related to one another than to the gorilla (Patterson et al., 2006; see Table 1), the family Hominidae is split into two subfamilies, the Gorillinae (encompassing the living genus Gorilla and its exclusive ancestors) and the Homininae, which includes humans, bonobos, chimpanzees, and their exclusive ancestors. Face and body skin coloration and pelage are unique for each species/subspecies; in captivity the facial coloration can vary between pink/tan, mottled, freckled, and black.

The theory of mind including such faculties as mental state attribution, empathy and even empathetic deception is a controversial criterion distinguishing the adult human alone among the hominids. An additional challenge to fields of research in which chimpanzees serve as a model is a proposal by the U.S.
