Studies of sexual selection show that both female choice and male-male competition can
influence the evolution and expression of male phenotypes. In this regard, it is important to …

This article analyzes the adaptations of the hindlimb of two Early Paleocene marsupials,
Mayulestes ferox and Pucadelphys andinus. This analysis is based on detailed comparisons …

In this study, the hindlimb of 12 species of tupaiids was analyzed functionally and compared
to that of primates, dermopterans, and chiropterans. Many aspects of the tupaiid hindlimb …

The ilium and ischiopubic bones of the pelvis arise from different regulatory pathways, and
as a result, they may be modular in their organization such that features on one bone may …

The locomotor category of vertical clingers and leapers has been dominated conceptually
from the beginning by its small-bodied representatives, galagos and tarsiers. Over the years …

Knowledge of the forces animals generate and are exposed to during locomotion is an
important prerequisite for understanding the musculoskeletal correlates of locomotor modes …

Apidium phiomense is the most common primate from the early Oligocene deposits of
Fayum, Egypt. It is known from hundreds of dental remains and dozens of skeletal remains …

We investigated locomotor and postural behavior during terminal branch feeding in order to
gain a better understanding of the motor capabilities of primates. We videotaped wild …

In earlier studies (von Koenigswald 1969; Delson 1973; Simons and Delson 1978; Szalay
and Delson 1979), the Miocene cercopithecids were regarded as belonging to a separate …

Jumping is a crucial behavior in fitness-critical activities including locomotion, resource
acquisition, courtship displays and predator avoidance. In primates, paleontological …
