Locomotor decoupling and the origin of hominin bipedalism [PDF]

, 2006
Theoretical adaptive landscapes and mathematical representations of key constraints of evolutionary and primate biology are used to propose a new hypothesis for the origin of hominin bipedalism.

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

Frontiers 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,

Uner Tan syndrome;Tan's theory for evolution of human bipedalism [PDF]

, 2014
  Uner Tan syndrome in Kars family (Turkey) was presented, with (UTS Type-II) and without infantile hypotonia (UTS Type-I), One case exhibited early-onset quadrupedal locomotion and late-onset bipedal locomotion.

The arboreal origins of human bipedalism [PDF]

, 2014
Almost a century and a half ago, Charles Darwin in The Descent of Man (1871: 141) highlighted the evolution of bipedalism as one of the key features of the human lineage, freeing the hands for carrying and for using and making tools. But how did it arise?

Bipedalism, Childhood, and Ritualisation of Human Sexual Behaviour: A Hominin Model Scenario of Ontogenetic Selection.

Bio Systems
In this paper, the term childhood denotes the ontogenetic developmental stage of weaned mammal infants who are still helpless and need to be nurtured and protected for survival.

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

The 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?

The 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.

Locomotion, posture, and the foramen magnum in primates: Reliability of indices and insights into hominin bipedalism

American Journal of Primatology, 2020
The position (FMP) and orientation (FMO) of the foramen magnum have been used as proxies for locomotion and posture in extant and extinct primates. Several indices have been designed to quantify FMP and FMO but their application has led to conflicting ...

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Unique enlargement of human soleus muscle for bipedalism at the expense of the ease of leg swing.

Journal of Biomechanics
Humans exhibit unique skeletal muscle morphologies that are known to matter in upright bipedalism. However, their relevance to the ease of leg swing, which limits locomotion performance, remains unclear. Here, we aimed to examine muscle mass distribution
