Am J Phys Anthropol 138:343-55. 2009..This lends support to Reynolds' suggestion that some primates use muscles to actively shift weight onto hind limbs to relieve stresses on forelimbs less well structured for weight support...

Department of Anatomical Sciences, Stony Brook University Medical Center, NY 11794 8081, USA
J Hum Evol 57:555-70. 2009..The upper limb presents a unique mosaic of derived (human-like) and primitive morphologies, the combination of which is never found in either healthy or pathological modern humans...
Maintenance of above-branch balance during primate arboreal quadrupedalism: coordinated use of forearm rotators and tail motionSusan G Larson
Department of Anatomical Sciences, Stony Brook University School of Medicine, New York 11794 8081, USA
Am J Phys Anthropol 129:71-81. 2006..The usefulness of a long tail as a balancing aid during arboreal locomotion highlights the puzzling nature of the evolutionary loss of a tail in the ape and human lineage...
Patterns of strain in the macaque ulna during functional activityB Demes
Department of Anatomical Sciences, School of Medicine, State University of New York, Stony Brook 11794 8081, USA
Am J Phys Anthropol 106:87-100. 1998..The lack of buttressing in the loaded plane and the somewhat counterintuitive bending direction recommend caution with regard to conventional interpretations of long bone cross-sectional geometry...
Telemetered electromyography of the supinators and pronators of the forearm in gibbons and chimpanzees: implications for the fundamental positional adaptation of hominoidsJ T Stern
Department of Anatomical Sciences, School of Medicine, Stony Brook University, Stony Brook, NY 11794 8081, USA
Am J Phys Anthropol 115:253-68. 2001..Since the greater range of forearm rotation characterizing apes is also best explained by adaptation to this behavior, we join previous authors who assert that it lies at the very origin of the Hominoidea...
Descriptions of the lower limb skeleton of Homo floresiensisW L Jungers
Department of Anatomical Sciences, Stony Brook University Medical Center, NY 11794 8081, USA
J Hum Evol 57:538-54. 2009..The metatarsus has a human-like robusticity formula, but the proximal pedal phalanges are relatively long and robust (and slightly curved). The hallux is fully adducted, but we suspect that a medial longitudinal arch was absent...
The foot of Homo floresiensisW L Jungers
Department of Anatomical Sciences, Stony Brook University Medical Center, Stony Brook, New York 11794 8081, USA
Nature 459:81-4. 2009..These new findings raise the possibility that the ancestor of H. floresiensis was not Homo erectus but instead some other, more primitive, hominin whose dispersal into southeast Asia is still undocumented...
Uniqueness of primate forelimb posture during quadrupedal locomotionS G Larson
Department of Anatomical Sciences, State University of New York at Stony Brook, Stony Brook, New York 11794 8081, USA
Am J Phys Anthropol 112:87-101. 2000..It is suggested that these features are components of functional adaptations to locomotion in an arboreal habitat, using clawless, grasping extremities...
