The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

The mechanism of labor in nonhuman primates: A look inside
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.
