Quantitative biomechanical assessment of locomotor capabilities of the stem archosaur Euparkeria capensis

open access: yesRoyal Society Open Science, 2023
Birds and crocodylians are the only remaining members of Archosauria (ruling reptiles) and they exhibit major differences in posture and gait, which are polar opposites in terms of locomotor strategies.

Embodied Niche Construction in the Hominin Lineage: Semiotic Structure and Sustained Attention in Human Embodied Cognition

open access: yesFrontiers in Psychology, 2014
Human evolution unfolded through a rather distinctive, dynamically constructed ecological niche. The human niche is not only generally terrestrial in habitat, while being flexibly and extensively heterotrophic in food-web connections.

Bipedalism or bipedalisms: The os coxae of StW 573

open access: yesJournal of Anatomy
Abstract There has been a long debate about the possibility of multiple contemporaneous species of Australopithecus in both eastern and southern Africa, potentially exhibiting different forms of bipedal locomotion.

Ticks, Hair Loss, and Non-Clinging Babies: A Novel Tick-Based Hypothesis for the Evolutionary Divergence of Humans and Chimpanzees

open access: yesLife, 2021
Human straight-legged bipedalism represents one of the earliest events in the evolutionary split between humans (Homo spp.) and chimpanzees (Pan spp.), although its selective basis is a mystery. A carrying-related hypothesis has recently been proposed in

Bipedal locomotion in zoo apes: Revisiting the hylobatian model for bipedal origins

open access: yesEvolutionary Human Sciences, 2022
Bipedal locomotion is a hallmark of being human. Yet the body form from which bipedalism evolved remains unclear. Specifically, the positional behaviour (i.e. orthograde vs. pronograde) and the length of the lumbar spine (i.e. long and mobile vs.

Muscle endurance: Is bipedalism the cause?

open access: yesFrontiers in Ecology and Evolution, 2022
One may ask if the transition to bipedalism from the condition of quadrupedalism, which occurred about 7 million years ago, has been the cause or consequence of a series of fundamental physiological muscular aspects including the cost of locomotion, a ...

Rôle des environnements dans les origines et l’évolution de la bipédie chez les hominidés : exemple des zones boisées sèches de l’Afrique

open access: yesRevue de Primatologie, 2022
In the literature, reference has often been made to the environments in which our ancestors lived, emphasizing dietary requirements and/or the importance of behaviours in these more or less wooded environments.

The influence of multiple variables on bipedal context in wild chimpanzees: implications for the evolution of bipedality in hominins

open access: yesFrontiers in Ecology and Evolution
Investigations into the role of selection in the origin of human bipedalism using ape models have relied heavily on behavioral frequency data. However, analysis of video of wild apes has the advantage of capturing the details of the entirety of each rare,

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

open access: yesThe Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

open access: yesThe Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.
