Human evolution and the obstetrical dilemma: The pelvic floor hypothesis
The Anatomical Record, EarlyView.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.

The effect of feeding on the respiratory activity of the sloth
Brazilian Journal of Medical and Biological Research, 2002 The aim of the present study was to confirm whether feeding influences the resting breathing rate and to observe possible alterations in blood gas and pH levels produced by feeding in unanesthetized sloths (Bradypus variegatus). Five adult male sloths (4.

Genomic data suggest parallel dental vestigialization within the xenarthran radiation
Peer Community Journal, 2023 The recent influx of genomic data has provided greater insights into the molecular basis for regressive evolution, or vestigialization, through gene loss and pseudogenization.

People and Nature, EarlyView.Abstract Coexistence with large carnivores becomes extremely difficult in areas where there are large number of attacks on humans. An understanding of the factors that explain the spatio‐temporal context of such attacks would guide policy and management to mitigate conflict, conserve carnivores and assist coexistence.

Adjusting Our Thinking About Feeding Animals: Fiber as the Metric for Mimicking Natural Diets
Zoo Biology, EarlyView.A typical effect of the change of an animal group to a diet higher in fiber: juveniles keep growing, animals of ideal body weight maintain their weight, and obese individuals lose weight. ABSTRACT Free‐ranging animals often ingest markedly different diets than their counterparts under human care, whether companion animals, production animals, or zoo ...
