Au. 1 Evolution … Australopithecus afarensis and africanus, and the other species above, are known as gracile australopithecines, because of their relatively lighter build, especially in the skull and teeth. Key physical features. Australopithecines include the genus Paranthropus (2.3–1.2 mya), which comprises three species of australopiths—collectively called the “robusts” because of their very large cheek teeth set in massive jaws. garhi Formerly Australopithecus, now Paranthropus †P. The name Paranthropus walkeri is under review and this species is often referred to as Paranthropus (or Australopithecus) aethiopicus. Bipedalism’s advantages over quadrupedalism include Australopithecus is a member of the subtribe Australopithecina, which also includes Ardipithecus and Praeanthropus, though the term "australopithecine" is sometimes used to refer only to members of Australopithecus. All three species share similar physical characteristics - a relatively small body and a ‘robust’ or strongly built skull including large lower jaws with extremely large molar teeth. bahrelghazali †A. garhi is the oldest possible species that may have used tools such as this. (a) sagittal crest, (b) nuchal crest, (c) dished face, (d) small molar teeth. Paranthropus robustus is an example of a robust australopithecine; they had very large megadont cheek teeth with thick enamel and focused their chewing in the back of the jaw.Large zygomatic arches (cheek bones) allowed the passage of large chewing muscles to the jaw and gave P. robustus individuals their characteristically wide, dish-shaped face.A large … This question may be completed independently or as a group exercise. africanus †A. There is considerable disagreement, … Australopithecina or Hominina is a subtribe in the tribe Hominini.The members of the subtribe are generally Australopithecus (cladistically including the genera Homo, Paranthropus, and Kenyanthropus), and it typically includes the earlier Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus.All these related species are now sometimes collectively termed australopiths … 9.
