3D analysis of hip joint mobility and the evolution of locomotor abilities in miocene hominoids
(University of Missouri--Columbia, 2013)The emergence of extant ape-like locomotor behaviors has become a defining issue in reconstructing ape evolution. Suspensory positional behaviors, such as antipronograde bridging, climbing, clambering and transfer, distinguish ... -
3D analysis of primate hindlimb joints : reconstructing positional abilities in extinct primates [abstract]
(2010)This study uses articulated 3D polygonal models of the pelvis and femur to simulate range of abduction during loading, and evaluates effects of different aspects of morphology on femoral postures. Continuous laser scan ... -
Determining the relations between canine crown height and root basal diameters and root length: implications for the hominin fossil record
(University of Missouri--Columbia, 2006)Canine reduction in hominins is one of the original apomorphies to appear in hominin evolution. Canine crown size is sexually dimorphic in most primates, sexual dimorphism is linked strongly to sexual selection; therefore ... -
Dimorphism and integration in the pelves of anthropoid primates
(University of Missouri--Columbia, 2016)The link between obstetric demand (natural selection for birth) and pelvic morphology in anthropoids has remained ambiguous for the past century. Though it is assumed that the dramatic sexual dimorphism seen in modern human ... -
Effects of hip joint orientation and skeletal torsion on human locomotor biomechanics and evolution
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 8/1/2024] Bipedal locomotion is a defining feature of the human lineage. However, the form of bipedality in different hominin taxa and the timing of emergence of a human-like striding bipedal gait have ... -
Estimating radial curvature in fragmentary hominin fossils : a comparative study in apes and humans [abstract]
(2010)Forearm bone curvature has been invoked in interpretation of fossil hominin behavior. Apes have curved radii, reflecting hypertrophied forearm musculature needed for below-branch arboreal locomotion and increased leverage ... -
Foot and ankle functional morphology in anthropoid primates and Miocene hominoids
(University of Missouri--Columbia, 2020)Locomotion is essential for survival in many taxa. It also varies greatly among organisms, including primates. Studying locomotor diversity in extant and fossil primates requires an understanding of form-function relationships. ... -
Functional morphology of the anthropoid talocrural joint
(University of Missouri--Columbia, 2008)The form and function of the talocrural joint of anthropoids is frequently used to infer positional behaviors of fossil catarrhines without clear and quantitative data to support these inferences. Specifically, greater ... -
Functional myology of the primate head and neck with implications for hominin evolution
(University of Missouri--Columbia, 2021)[EMBARGOED UNTIL 5/1/2025] The primate nuchal region has been widely cited as reflecting postural and locomotor behaviors. Postural and locomotor reconstructions of fossil primates, particularly fossil hominins, have relied ... -
Hip structure and locomotion in ambulatory and cursorial carnivores reinvestigated [abstract]
(2010)Understanding how the femoral head articulates with the acetabulum of the pelvis should allow one to infer the pattern of hip mobility in living and fossil species. In 1977, Jenkins and Camazine analyzed cineradiographic ... -
Population history at the microscale : craniometrics of Cayo Santiago macaques
(2010)Being able to understand the effects of relatedness on adult cranial morphology has implications for inferring population histories, and for informing us about the influence of genetics on cranial form among human populations. ... -
Second rib curvature in apes and humans and implications for the evolution of thoracic shape in early hominins [abstract]
(2010)Thoracic form in humans is often described as "barrel-shaped" with a broad upper rib cage, a condition different from great apes, who have a "cone-shaped" thorax and narrower upper rib cage. The earliest Australopithecus ...
