Arboreal primates have distinctive intrinsic hand proportions compared with many other
mammals. Within Euarchonta, platyrrhines and strepsirrhines have longer manual proximal …

Questions surrounding the origin and early evolution of primates continue to be the subject
of debate. Though anatomy of the skull and inferred dietary shifts are often the focus …

Recent work has shown that, despite being craniodentally more derived, Australopithecus
africanus had more apelike limb-size proportions than A. afarensis. Here, we test whether …

The hands of apes and humans differ considerably with regard to proportions between
several bones. Of critical significance is the long thumb relative to other fingers, which is the …

The evolution of prehensile hands is a dominant theme inherent to theories of primate
origins. However, there is strong disagreement among proponents of various models of …

Fine-branch models have long played a central role in primate evolutionary research.
Nevertheless, recent studies of positional behavior in nonprimate arboreal mammals have …

The primate fossil record suggests that terrestriality was more common in the past than it is
today, particularly among cercopithecoid primates. Whether or not a fossil primate habitually …

The hands and feet of primates fulfill a variety of biological roles linked with food acquisition
and positional behavior. Current explanations of shape differences in cheiridial morphology …

New York: Springer-Verlag, pp. 245–256) used a theoretical biomechanical analysis to …

The partial skeleton of Pierolapithecus, which provides the oldest unequivocal evidence of
