Human beings have been credited with unparalleled capabilities for digital prehension
grasping. However, grasping behaviour is widespread among tetrapods. The propensity to …

This review examines the proximate, ecological, and evolutionary determinants of energy
expenditure in humans and primates, with an emphasis on empirical measurements of total …

Arboreal mammals navigate a highly three dimensional and discontinuous habitat. Among
arboreal mammals, squirrels demonstrate impressive agility. In a recent “viral” YouTube …

Primates of modern aspect (euprimates) are characterized by a suite of characteristics (eg,
convergent orbits, grasping hands and feet, reduced claws, and leaping), but the selective …

Objectives The disappearance of the North American plesiadapoids (stem primates, or
plesiadapiforms) in the latest Paleocene has been attributed to competition with rodents …

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 need to maintain stability on narrow branches is often presented as a major selective
force shaping primate morphology, with adaptations to facilitate grasping receiving particular …

Locomotion is precarious in an arboreal habitat, where supports can vary in both diameter
and level of compliance. Several previous studies have evaluated the influence of substrate …

The fossil record of early primates is largely comprised of dentitions. While teeth can indicate
phylogenetic relationships and dietary preferences, they say little about hypotheses …

An arboreal lifestyle is thought to be central to primate origins, and most extant primate
species still live in the trees. Nonetheless, terrestrial locomotion is a widespread adaptation …
