Comparative Functional Morphology of Human and Chimpanzee Feet …
To comparatively investigate the morphological adaptation of the human foot for achieving robust and efficient bipedal locomotion, we develop three-dimensional finite element models of the human and chimpanzee feet. Foot bones and the outer surface ...
Chimpanzee Feet vs. Human Feet - CoreWalking
Chimpanzee feet are amazing to explore if you are interested in how humans walk, and two recent studies have shed interesting new light on our similarities and differences depending on how you interpret them.
Hands and feet interface directly with the environment through contact with ground and tree surfaces, food items, and other physical objects. This gross anatomical study focuses on both hands and feet in the same individuals and across four species and analyzes soft and hard tissue.
Methods: We used a high-speed motion capture system to measure three-dimensional kinematics of the ankle and midfoot joints in two male chimpanzees during three locomotor modes: terrestrial quadrupedalism on a flat runway, arboreal quadrupedalism on a horizontally oriented tree trunk, and climbing on a vertically oriented tree trunk.
Form and function of the human and chimpanzee forefoot: …
Jul 28, 2016 · The drop-off in dorsiflexion angle magnitude is steeper in chimpanzees, perhaps due to the oblique orientation of their feet relative to the direction of travel during terrestrial locomotion. In this position the hallux is directed anteromedially, and the lateral digits are …
chimpanzee foot anatomy enables a versatile locomotor repertoire, and urge caution when using foot joint morphology to reconstruct arboreal behavior in fossil hominins. INTRODUCTION
Muscle dimensions of the foot in the orangutan and the chimpanzee
Jul 16, 2012 · The morphology of the bones and joints enable the orangutan foot to function as a suspensory supporting organ, whereas chimpanzees have a plantigrade foot.
The muscular anatomy of the chimpanzee foot - ResearchGate
Feb 1, 1973 · We examined modifications in the interosseous muscles of the chimpanzee, gibbon, spider monkey, and Japanese macaque in terms of the shift in the functional foot axis.
Comparison of a chimpanzee (A) and human (B) foot with …
There are 26 bones in each foot (52 in total), meaning that roughly a quarter of the human skeleton consists of foot bones.
Chimpanzee ankle and foot joint kinematics: Arboreal versus
Therefore, we argue that chimpanzee foot anatomy enables a versatile locomotor repertoire, and urge caution when using foot joint morphology to reconstruct arboreal behavior in fossil hominins. Keywords: biomechanics; climbing; foot morphology; human evolution; primate locomotion.
