From speculations about their close relatives, the gorilla and chimpanzee, A. afarensis’ probable social structure can be presumed. The species was named by Johanson and Taieb in 1973. This discovery of a skeleton lead to a heated debate over the validity of the species. The species eventually was accepted by most researchers as a new species of australopithecine and a likely candidate for a human ancestor. Australopithecus afarensis existed between 3.9 and 3.0 million years ago. A. afarensis is classified as an ape, not a human. It is a Hominid, which is an ape closely related to human beings. In conclusion, A. afarensis was one of the first homonids to diverge from the species of apes and on toward the evolution of the human species. Because of their intermediate position in their characteristics, A. afarensis can be differentiated as one of the first steps on position in their characteristics, A....
