The evolution of compliance in the human lateral mid-foot. [PDF]

open access: yes, 2013
Fossil evidence for longitudinal arches in the foot is frequently used to constrain the origins of terrestrial bipedality in human ancestors. This approach rests on the prevailing concept that human feet are unique in functioning with a relatively stiff ...

Early Hominin Movement Patterns at Laetoli, Northern Tanzania

open access: yesPaleoAnthropology
The site of Laetoli in northern Tanzania is famous for its preservation of 3.66-million-year-old footprint trails, among which are several belonging to an upright walking hominin (Day and Wickens, 1980; Leakey and Hay, 1979; Masao et al., 2016; McNutt et

Muscle MRI and Muscle Ultrasound Applications in MND/ALS: Academic Insights and Clinical Opportunities

open access: yesEuropean Journal of Neurology, Volume 33, Issue 3, March 2026.
ABSTRACT Background There is an unmet need for the clinically relevant ALS biomarkers to facilitate an accurate diagnosis in suspected cases, monitor disease progression and evaluate response to therapy in clinical trials. While the MND/ALS literature is dominated by innovative brain studies, motor disability in ALS is primarily driven by neurogenic ...

Contemporary and Historical Evidence to Suggest that Women’s Preference for Age at Birth of First Child Remains Consistent Across Time [PDF]

open access: yes, 2014
Women’s ability to reproduce is restricted by menarche and menopause. First children are, however, not typically born until some years after the onset of puberty. Other factors therefore contribute towards this delay. In this context, women’s hips do not

The African ape-like foot of Ardipithecus ramidus and its implications for the origin of bipedalism

open access: yeseLife, 2019
The ancestral condition from which humans evolved is critical for understanding the adaptive origin of bipedal locomotion. The 4.4 million-year-old hominin partial skeleton attributed to Ardipithecus ramidus preserves a foot that purportedly shares ...

Feeding in Forest Chimpanzees: Do Food Type and Canopy Location Predict Positional Behavior?

open access: yesAmerican Journal of Biological Anthropology, Volume 189, Issue 2, February 2026.
Ngogo chimpanzees from Kibale National Park, Uganda use versatile postures, like suspension, more when eating leaves than other foods. However, in the terminal canopy, eating fruit is most associated with versatility. Food type and availability, in different combinations, produce similar behaviors.

Evidence to Suggest that Copulatory Vocalizations in Women Are Not a Reflexive Consequence of Orgasm [PDF]

open access: yes, 2011
The current studies were conducted in order to investigate the phenomenon of copulatory vocalizations and their relationship to orgasm in women. Data were collected from 71 sexually active heterosexual women (M age = 21.68 years ± .52) recruited from the

Trabecular bone structure correlates with hand posture and use in hominoids [PDF]

open access: yes, 2013
Bone is capable of adapting during life in response to stress. Therefore, variation in locomotor and manipulative behaviours across extant hominoids may be reflected in differences in trabecular bone structure.

Human lower limb muscle cross sectional area scales with positive allometry reflecting bipedal evolutionary history

open access: yesFrontiers in Earth Science
Introduction: Muscle cross-sectional area is an important variable for understanding force generating potential and locomotor adaptation. Geometric scaling predicts area scales proportionally to body mass2/3.
