The biomechanics of leaping in gibbons
Gibbons are skilled brachiators but they are also highly capable leapers, crossing distances in excess of 10 m in the wild. Despite this impressive performance capability, no detailed biomechanical studies of leaping in gibbons have been undertaken to date. We measured ground reaction forces and derived kinematic parameters from high‐speed videos during gibbon leaps in a captive zoo environment. We identified four distinct leap types defined by t…
Masticatory loading and bone adaptation in the supraorbital torus of developing macaques
Research on the evolution and adaptive significance of primate craniofacial morphologies has focused on adult, fully developed individuals. Here, we investigate the possible relationship between the local stress environment arising from masticatory loadings and the emergence of the supraorbital torus in the developing face of the crab‐eating macaque Macaca fascicularis . By using finite element analysis (FEA), we are able to evaluate the hypothes…
Origin of Human Bipedalism As an Adaptation for Locomotion on Flexible Branches
Human bipedalism is commonly thought to have evolved from a quadrupedal terrestrial precursor, yet some recent paleontological evidence suggests that adaptations for bipedalism arose in an arboreal context. However, the adaptive benefit of arboreal bipedalism has been unknown. Here we show that it allows the most arboreal great ape, the orangutan, to access supports too flexible to be negotiated otherwise. Orangutans react to branch flexibility l…
Biomechanics: Folia Primatologica 2004, Vol. 75, No. 4
In the study of primate adaptation, although the mechanics of the locomotor and masticatory systems in particular are dominant elements in determining their form, biomechanics, more often than not, is given nothing more than lip service. In this volume, we have gathered together papers from both a theoretical and practical perspective, illustrating
Energy transformation during erect and ‘bent-hip, bent-knee’ walking by humans with implications for the evolution of bipedalism
Reconstructing the mechanics of quadrupedalism in an extinct hominoid
Traditionally, analogising comparative anatomical approaches, working on features of individual bony elements, have led to the Miocene hominoids Proconsul heseloni and P. nyanzae being described as arboreal, with a variety of possible locomotion modes. Whilst most researchers seemingly agree that quadrupedal was one of the most frequently adopted modes, any deeper knowledge about the kinematical characteristics of such quadrupedalism is very limi…

Segment inertial properties of primates: New techniques for laboratory and field studies of locomotion
Studies of the dynamics of locomotor performances depend on knowledge of the distribution of body mass within and between limb segments. However, these data are difficult to derive. Segment mass properties have generally been estimated by modelling limbs as truncated cones, but this approach fails to take into account that some segments are of elliptical, not circular, cross section; and further, the profiles of real segments are generally curved…
A system for 2- and 3D kinematic and kinetic analysis of locomotion, and its application to analysis of the energetic efficiency of jumping locomotion
Kinematic analysis of film and video recordings is a standard technique in studies of the mechanics of locomotion. With the addition of segment mass data, kinematic analysis may be extended to estimate the forces, torques and bending loads imposed on limb segments, using inverse dynamic analysis. A software/hardware system for 2- and 3D kinematic and dynamic analysis is described, based on digitized images from multiple video cameras and featurin…
