Infant-carrying mechanisms in a natural environment: The case of Qashqai nomad
Infant carrying and more generally load carrying may impact bipedal locomotion and thus the energy cost of the daily activities, in living people but also in our ancestors. In order to improve our knowledge of infant carrying strategies we investigate the biomechanics of infant carrying in a non-mechanised group. The Qashqai are nomadic people who still carry loads and infants habitually without any daily assistance in varied natural environments…
A helping hand: Investigating 3D motion of human hand bones during Palaeolithic tool behaviours
The morphological configuration of the wrist of Homo sapiens and Neanderthals has traditionally been interpreted as biomechanically advantageous for frequent lithic tool use and production. However, this interpretation remains to be demonstrated. We present a proof of concept study that is the first to investigate the 3D kinematics of the hand bones of modern humans during in vivo simulated Palaeolithic tool behaviours. We used the bi-planar X-ra…
Body mass estimation from footprint size in hominins
Foot anatomy, walking energetics, and the evolution of human bipedalism
Marches bipède et quadrupède du babouin olive (Papio anubis): Activité Musculaire Comparée Et Perspectives Évolutives
La marche bipède humaine est particulièrement raffinée et efficace. Les primates non-humains (PNHs), quant à eux, utilisent la bipédie occasionnellement au sein d’un répertoire posturo-locomoteur souvent varié. Dans le contexte de l’évolution des modes locomoteurs chez les primates (incluant les hominines), une hypothèse suggère l’existence d’un mécanisme de contrôle basique et similaire en bipédie et en quadrupédie. La tester nécessite une obser…
Biomechanical implications of walking with indigenous footwear
OBJECTIVES: This study investigates biomechanical implications of walking with indigenous "Kolhapuri" footwear compared to barefoot walking among a population of South Indians. MATERIALS AND METHODS: Ten healthy adults from South India walked barefoot and indigenously shod at voluntary speed on an artificial substrate. The experiment was repeated outside, on a natural substrate. Data were collected from (1) a heel-mounted 3D-accelerometer recordi…
Gait characteristics and spatio‐temporal variables of climbing in bonobos ( Pan paniscus )
Although much is known about the terrestrial locomotion of great apes, their arboreal locomotion has been studied less extensively. This study investigates arboreal locomotion in bonobos (Pan paniscus), focusing on the gait characteristics and spatio-temporal variables associated with locomotion on a pole. These features are compared across different substrate inclinations (0°, 30°, 45°, 60°, and 90°), and horizontal quadrupedal walking is compar…
Understanding the evolution of the windlass mechanism of the human foot from comparative anatomy: Insights, obstacles, and future directions
Humans stand alone from other primates in that we propel our bodies forward on a relatively stiff and arched foot and do so by employing an anatomical arrangement of bones and ligaments in the foot that can operate like a “windlass.” This is a significant evolutionary innovation, but it is currently unknown when during hominin evolution this mechanism developed and within what genera or species it originated. The presence of recently discovered f…
Using primate models to study the evolution of human locomotion: Concepts and Cases
This note introduces the types of models used in functional morphological research in order to clarify certain semantic issues and to present some examples of the use of extant model species to contribute to our understanding of bipedal locomotion. The existing models fall into two broad categories: “abstraction models” are simplifications/abstractions of living organisms, whereas “comparative models” are extant organisms used as models or analog…
Bipedal versus Quadrupedal Hind Limb and Foot Kinematics in a Captive Sample of Papio anubis: Setup and Preliminary Results
The biomechanics of leaping in gibbons
Gibbons are skilled brachiators but they are also highly capable leapers, crossing distances in excess of 10 m in the wild. Despite this impressive performance capability, no detailed biomechanical studies of leaping in gibbons have been undertaken to date. We measured ground reaction forces and derived kinematic parameters from high‐speed videos during gibbon leaps in a captive zoo environment. We identified four distinct leap types defined by t…

Functional analysis of the gibbon foot during terrestrial bipedal walking: Plantar pressure distributions and three‐dimensional ground reaction forces
This paper gives a detailed analysis of bipedal walking in the white‐handed gibbon, based on collected pressure and force data. These data were obtained from four gibbons in the Wild Animal Park, Planckendael, Belgium, by using a walkway with integrated force plate and pressure mat. This is the first study that collects and describes dynamic plantar pressure data of bipedally walking gibbons, and combines these with force plate data. The combinat…
Dynamic plantar pressure distribution during terrestrial locomotion of bonobos ( Pan paniscus )
We collected high‐resolution plantar pressure distributions of seven bonobos during terrestrial bipedal and quadrupedal locomotion (N = 146). Functional foot length, degree of hallux abduction, and total contact time were determined, and plots, showing pressure as a function of time for six different foot regions, were generated. We also studied five adult humans for comparison (N = 13). Both locomotion types of the bonobo show a large variation …
Segment and joint angles of hind limb during bipedal and quadrupedal walking of the bonobo ( Pan paniscus )
We describe segment angles (trunk, thigh, shank, and foot) and joint angles (hip, knee, and ankle) for the hind limbs of bonobos walking bipedally (“bent‐hip bent‐knee walking,” 17 sequences) and quadrupedally (33 sequences). Data were based on video recordings (50 Hz) of nine subjects in a lateral view, walking at voluntary speed. The major differences between bipedal and quadrupedal walking are found in the trunk, thigh, and hip angles. During …
