15 صفحه اولLimb-size proportions in Australopithecus afarensis and Australopithecus africanus.
Previous analyses have suggested that Australopithecus africanus possessed more apelike limb proportions than Australopithecus afarensis. However, due to the errors involved in estimating limb length and body size, support for this conclusion has been limited. In this study, we use a new Monte Carlo method to (1) test the hypothesis that A. africanus had greater upper:lower limb-size proportion...
متن کاملMolar microwear textures and the diets of Australopithecus anamensis and Australopithecus afarensis.
Many researchers have suggested that Australopithecus anamensis and Australopithecus afarensis were among the earliest hominins to have diets that included hard, brittle items. Here we examine dental microwear textures of these hominins for evidence of this. The molars of three Au. anamensis and 19 Au. afarensis specimens examined preserve unobscured antemortem microwear. Microwear textures of ...

متن کاملHumerus of Robust Australopithecus
McHenry's (1) discriminant analysis of the large robust Australopithecus humerus, KNM-ER 739, from strata east of Lake Rudolph, Kenya (2), demonstrated that it is morphologically and, presumably, functionally distinct from the humeri of extant large hominoids. He concluded that his results could not determine whether this early hominid used its forelimbs for both manipulation and locomotion or ...
