Human bipedalism and body-mass index

Scientific Reports, 2017
Body-mass index, abbreviated as BMI and given by M/H 2 with the mass M and the height H, has been widely used as a useful proxy to measure a general health status of a human individual.

Bipedality in chimpanzee (Pan troglodytes) and bonobo (Pan paniscus):Testing hypotheses on the evolution of bipedalism

, 2002
A host of ecological, anatomical, and physiological selective pressures are hypothesized to have played a role in the evolution of hominid bipedalism. A referential model, based on the chimpanzee (Pan troglodytes) and bonobo (Pan paniscus), was used to ...

Comparative cranial anatomy of Homo sapiens and Canis lupus familiaris: morphological, functional, and educational perspectives with a glance to biodiversity

Journal of Biological Research
Cranial morphology reflects a species’ evolutionary history, functional adaptations, and environmental interactions. This comparative anatomical study examines the key structural differences between the cranium of humans (Homo sapiens) and that 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

The mechanics of the gibbon foot and its potential for elastic energy storage during bipedalism [PDF]

, 2008
The mechanics of the modern human foot and its specialization for habitual bipedalism are well understood. The windlass mechanism gives it the required stability for propulsion generation, and flattening of the arch and stretching of the plantar ...

Does Bipedalism Confer an Advantage to Lizards Sprinting Over Obstacles?

, 2017
Terrestrial animals evade predators and capture prey by running over uneven and highly variable terrain. Characterizing the mechanisms to traverse obstacles can clarify crucial aspects of how animals interact with their environment.

The human bipedalism : epistemology, paleo-anthropology, metaphysics

, 2015
La paléoanthropologie utilise la bipédie comme critère d'interprétation des vestiges fossiles permettant d'établir leur appartenance à la lignée humaine. Ainsi, la bipédie devient une caractéristique propre à la lignée humaine et qui en marque l'origine.

On the simple calculation of walking efficiency without kinematic information for its convenient use

Journal of Physiological Anthropology, 2019
Background Since walking is a daily activity not to require the maximal effort in healthy populations, a very few universal bio-parameters and/or methods have been defined to evaluate individual walking characteristics in those populations. A concept of “

Bipedalism and pelvic floor disorders, an evolutionary medical approach

Continence Reports
Evolutionary medicine can help to better understand the basis of pelvic floor disorders. Some evidences of the anthropological literature are reviewed, with emphasis on the paleontological clues and phylogenetic comparison of cephalo-pelvic relations in ...
