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. australopithecines are gracile and robust. sediba an interesting question. As mentioned, it is categorized as a gracile form of australopith. 19-35 times their size. Gracile australopithecines shared several traits with modern apes and humans and were widespread throughout Eastern and Southern Africa as early as 4 to as late as 1.2 million years ago. Australopithecus afarensis, or the "southern ape from Afar," is a well-known species due to the famous "Lucy" specimen. Exercise 6 Examine the following illustration.

True or False: A C/P3 hone involves the upper canine sliding across the lower first premolar. Being bipedal could have been advantageous to the early hominins because it allows for better control of body temperature. Which of the following is NOT considered to be a robust australopithecine?

However, the validity of Paranthropus is contested, and it is sometimes considered to be synonymous with Australopithecus. is not considered a human ancestor . The first species to be identified as Australopithecus received that name in 1925, and, after nearly a century of discoveries, paleoanthropologists are able draw upon a fairly rich storehouse of fossil hominin specimens from Africa. Which of the following is NOT considered a robust australopithecine? A. Australopithecus africanus. Eventually, scientists recognized that the 'robust' forms were different enough to be in their own species, originally called Australopithecus robustus.Later, the three robust species (aethiopicus, boisei, and robustus) were recognized as being different enough .
