An understanding of the evolution of human bipedalism can provide valuable insights into
the biomechanical and physiological characteristics of locomotion in modern humans. The …

The vertical‐climbing account of the evolution of locomotor behavior and morphology in
hominid ancestry is reexamined in light of recent behavioral, anatomical, and …

The positional behavior of habituated adult chimpanzees and baboons was observed for
784 hr in a year‐long study. Comparisons between species were made to establish the …

Scapular morphology is predictive of locomotor adaptations among primates, but this
skeletal element is scarce in the hominin fossil record. Notably, both scapulae of the juvenile …

Field observations of two sympatric pitheciine species reveal that the positional repertoire of
the white‐faced saki, Pithecia pithecia, is dominated by leaping behaviors, whereas the …

As recently stressed by the philosopher of science Leandro Assis, a decline in the number of
phylogenetic hypotheses based on morphological evidence has become a pronounced …

Mechanical hypotheses concerning the function of chimpanzee anatomical specializations
are examined in light of recent positional behavior data. Arm‐hanging was the only common …

Apes, members of the superfamily Hominoidea, possess a distinctive suite of anatomical
and behavioral characters which appear to have evolved relatively late and relatively …

This paper supplies quantitative data on the hind‐and forelimb musculature of common
chimpanzees (Pan troglodytes) and calculates maximum joint moments of force as a …

The strain environment of the tibial midshaft of two female macaques was evaluated through
in vivo bone strain experiments using three rosette gauges around the circumference of the …
