Quantitative Study of Elbow Ligaments in Modern Humans (Homo sapiens) and Common Chimpanzees (Pan troglodytes)

American Journal of Biological Anthropology, Volume 190, Issue 3, July 2026.
Ligaments are key structures for stabilizing joints and for sending proprioceptive information to the brain. Nevertheless, their anatomical characteristics have been understudied in the comparative anatomy of primates. The elbow ligaments show a similar gross anatomy in humans and chimpanzees, but their components have different relative sizes in the ...

First Detailed Anatomical Study of Bonobos Reveals Intra-Specific Variations and Exposes Just-So Stories of Human Evolution, Bipedalism, and Tool Use

Frontiers in Ecology and Evolution, 2018
Just-so stories are prominent in human evolution literature because of our tendency to create simple progressionist narratives about our “special” place in nature, despite the fact that these stories are almost exclusively based on hard tissue data.

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.

Natural selection, genetic drift, and trait correlation shaped hominin midfoot evolution

Nature Communications
The foot has undergone significant morphological change throughout the hominin lineage as our extinct relatives evolved to walk upright. The midfoot displays key adaptations for terrestrial bipedal locomotion, and is therefore considered a target of ...

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

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 ...
