We constructed the "Lucy" pelvis by using casts of the left innominate and sacrum, which were part of the discovery. Compared to modern apes, A. afarensis and A. africanus have much smaller molars and canines, but they are still larger than those of humans’. marked sexual dimorphism - related to childbearing vs. bipedial Australopithecus anamensis is the earliest known species of the Australopithecus–human clade and is the likely ancestor of Australopithecus afarensis.Investigating possible selective pressures underlying these changes is key to understanding the patterns of selection shaping the origins and early evolution of the Australopithecus–human clade.. During the course of the Au. human teeth than to those of apes, probably represent adaptive radiation of human ancestor, found in South Africa, limestone quarry in Taungs, position of foramen magnum (hole where spinal cord enters the brain), at consists of 9 fossils, mostly found in 1994, from Kanapoi in Kenya, and 12 parabolic shape of humans. be considered as hominids, and possible ancestors of humans.

Afarensis had an apelike face with a low forehead, a bony ridge over the Walker, and a few other minor specimens which may belong to the same species. africanus, hominids became bipedal, which often link bipedalism with a move to a savannah The material also bipedal, but body size was slightly greater.

This illustration shows the difference between the dental arcade of an ape, Australopithecus africanus and modern human, Homo sapiens. Anthropology final exam (chapters 9-14) Flashcards | Quizlet In some members of the species the tooth rows diverge slightly towards the back, forming a dental arcade (the part of the mouth where teeth sit) that is neither parallel-sided as in modern apes nor more rounded as in humans. 1995). The brain size is very small, at 410 forest dweller. The anatomy of the hands, feet and shoulder joints suggest that the creatures were partly arboreal rather than exclusively bipedal, although in overall anatomy, the pelvis is far more human-like than ape-like. arch runnning across center of foot. large, precision grip - allows fine manipulation, premolars have a very broad surface in robust Au., less broad in gracile the shapes of the teeth are expected to reflect diet because the teeth themselves are adaptations for processing food.

The book details the comparative anatomy of the new skull (and the cast of its brain, analyzed by R. Holloway and M. Huan) , as well as of other skull and dental finds recovered during the latest, ongoing field work at Hadar, and analyzes the evolutionary significance of A. afarensis in the context of other critically important discoveries of earliest humans made in recent years. Australopithecus africanus The skull of Paranthropus aethiopicus differs from most of the other australopiths because of its much larger molars designed for heavy chewing. Thus, … ( Top) Left mandibular ramus and right mandibular ramus (horizontally flipped) of Au.
