Factoring the Proto-biped Infant into the Origin of Bipedalism [PDF]
, 2019 This thesis applies a single test method to a high number of proposed explanations (models) of hominin bipedalism. This has not been undertaken previously, due largely to the very variable ways in which the models have been built, and the ...

Form and function of the human and chimpanzee forefoot: implications for early hominin bipedalism
Scientific Reports, 2016 During bipedal walking, modern humans dorsiflex their forefoot at the metatarsophalangeal joints (MTPJs) prior to push off, which tightens the plantar soft tissues to convert the foot into a stiff propulsive lever.

The Anatomical Record, 2018 The third metacarpal has been a focus of study when examining questions surrounding early hominin locomotion since this bone is adapted to the diverse range of positional behaviors performed by extant hominoids.

Data from: The African ape-like foot of Ardipithecus ramidus and its implications for the origin of bipedalism [PDF]
, 2019 The ancestral condition from which humans evolved is critical for understanding the adaptive origin of bipedal locomotion. The 4.4 million-year-old hominin partial skeleton attributed to Ardipithecus ramidus preserves a foot that purportedly shares ...

The dynamics of hylobatid bipedalism: evidence for an energy-saving mechanism? [PDF]
, 2006 When gibbons travel through the forest canopy, brachiation is alternated with short bipedal bouts over horizontal boughs. We know, from previous research, that brachiation is a very efficient locomotor mode that makes use of a pendulum-like exchange of ...

Kinematic movement analysis of change from quadrupedalism to bipedalism [PDF]
Einstein (São Paulo), 2008 Objective: To assess the joint’s kinematics of the trunk, hip, knee and ankle in the sagittal plane during the postures changes from quadrupedalism to bipedalism. Methods: Twelve volunteers participated in this study: six female and six males, aged 20 to

Influence of trunk structure on posture transition from quadrupedalism to bipedalism
, 2017 An effective strategy for walking over rough terrain, flat plane, and wreckage includes transitioning from quadrupedal to bipedal locomotion. In this study, we designed a trunk mechanism that provides successful posture transition from quadrupedalism to ...
