Journal ArticleDOI
The locomotor anatomy of Australopithecus afarensis.
Jack T. Stern,Randall L. Susman +1 more
TL;DR: It is demonstrated that A. afarensis possessed anatomic characteristics that indicate a significant adaptation for movement in the trees, and it is speculated that earlier representatives of the A.Afarensis lineage will present not a combination of arboreal and bipedal traits, but rather the anatomy of a generalized ape.
Journal ArticleDOI
Arboreality and bipedality in the Hadar hominids.
TL;DR: Consideration of the ecology at Hadar, in conjunction with modern primate models, supports the notion of arboredality in these earliest australopithecines and provides additional evidence on limb and pedal proportions and on the functional anatomy of the hip, knee and foot, indicating that the bipedality practiced at hadar differed from that of modern humans.
Journal ArticleDOI
The kinetics of primate quadrupedalism: "hindlimb drive" reconsidered
Brigitte Demes,Susan G. Larson,Jack T. Stern,William L. Jungers,A.R. Biknevicius,Daniel Schmitt +5 more
TL;DR: The results support the overall conclusion of Kimura et al. (1979) that peak vertical forces are relatively low on the primate forelimb, but also show some variation most probably related to locomotor mode.
Journal ArticleDOI
Patterns of strain in the macaque tibia during functional activity.
TL;DR: The measured distribution of strains in the rhesus monkey ulna indicates that mediolateral bending, rather than anteroposterior bending, is the predominant loading regime, with the neutral axis of bending running from anterior and slightly medial to posterior and slightly lateral.
Journal ArticleDOI
Functional Morphology of Homo habilis.
Randall L. Susman,Jack T. Stern +1 more
TL;DR: The skeleton represents a mosaic of primitive and derived features, indicating an early hominid which walked bipedally and could fabricate stone tools but also retained the generalized hominoid capacity to climb trees.
