It should be noted that these defining characteristics apply to both the ‘gracile’ (Australopithecus) and ‘robust’ (Paranthropus) varieties. Ar. The Australopithecus species, referred to as Australopithecines, had features that were both human-like and ape-like. Australopithecus afarensis is an extinct species of australopithecine which lived from about 3.9–2.9 million years ago (mya) in the Pliocene of East Africa.The first fossils were discovered in the 1930s, but major fossil finds would not take place until the 1970s. A. afarensis walked on two legs but still had the long arms for climbing trees. While the canine tooth is apelike in some respects, it does not exhibit the classic interlocking honing complex (where the inner side of the upper canine sharpens itself against the lower premolar [or bicuspid]). We, along with the other apes, split off from chimps around six or seven million years ago. Did Australopithecus afarensis walk upright? Animal fossils, pollen, and other evidence associated with Ar. Its pelvis and lower chest resemble those of Homo, while other traits resemble those of Australopithecus. The remains of Ar. This opinion changed when new evidence showed this species had many features intermediate between apes and humans. The tibia (shinbone) exhibits anatomy at both the knee and ankle ends characteristic of later bipedal hominins. Afarensis matured at a faster rate than humans. Approximate time ranges of sites yielding australopith fossils. This finding was unexpected given that chimpanzees are the closest living relatives of humans. The upper end of the tibia (shin bone) shows an expanded area of bone and a human-like orientation of the ankle joint, indicative of regular bipedal walking (support of body weight on one leg at the time). Originally discovered in 1965 by a Harvard team, more fossils were found in the decades since. Bipedalism, however, appears to have been established in the six-million-year-old Orrorin tugenensis, a pre-Australopithecus found in the Tugen Hills near Lake Baringo in central Kenya.

Australopithecus anamensis lived about 4.2 million years ago. kadabba and may belong to another species of early hominin. They tended to have longer arms that seemed well-suited to climbing. Biological and Biomedical study Another candidate for the earliest hominin is classified in the genus Ardipithecus (5.8–4.4 mya).

Anthropologist Meave Leakey was responsible for officially naming the species in 1995. The general term australopith (or australopithecine) is used informally to refer to members of the genus Australopithecus. Australopithecus, (Latin: “southern ape”) (genus Australopithecus), group of extinct primates closely related to, if not actually ancestors of, modern human beings and known from a series of fossils found at numerous sites in eastern, north-central, and southern Africa. In contrast, remains older than six million years are widely regarded to be those of fossil apes. However, their skeletons show that they walked upright.
