The evolution of locomotion in archosaurs
Archosaurian reptiles evolved a more erect posture and parasagittal gait early on. Early dinosaurs were the first habitual striding bipeds, a trait retained by living birds. Yet there is much more to archosaur locomotor evolution than these two transitions. I review our understanding of the pattern of locomotor evolution from the first archosaurs to Crocodylia and Neornithes, outlining where tr...

15 صفحه اولLocomotion, Obstetrics, and the Evolution of the Homo Pelvis
The human pelvis plays important functional roles in locomotion and in the birthing of babies. The pelvis acts as a rigid lever during two-legged (bipedal) locomotion, which allows us to stabilize our hip and trunk when body weight is supported on a single leg, and it also operates to effectively transmit body weight from the trunk to the support leg. The pelvis is also important to human birth...
متن کاملMajor Transformations in the Evolution of Primate Locomotion
Compared to other mammalian orders, Primates use an extraordinary diversity of locomotor behaviors, which are made possible by a complementary diversity of musculoskeletal adaptations. Primate locomotor repertoires include various kinds of suspension, bipedalism, leaping, and quadrupedalism using multiple pronograde and orthograde postures and employing numerous gaits such as walking, trotting,...
متن کاملFossils, feet and the evolution of human bipedal locomotion.
We review the evolution of human bipedal locomotion with a particular emphasis on the evolution of the foot. We begin in the early twentieth century and focus particularly on hypotheses of an ape-like ancestor for humans and human bipedal locomotion put forward by a succession of Gregory, Keith, Morton and Schultz. We give consideration to Morton's (1935) synthesis of foot evolution, in which h...
