Body size is a key determinant of male fighting ability and reproductive success in many
animal species, but relationships between these variables have only rarely been examined …

In primates and other mammals, the capacity to generate a wide maximum jaw gape is an
important performance variable related to both feeding and nonfeeding oral behaviors, such …

Body and canine size dimorphism in fossils inform sociobehavioral hypotheses on human
evolution and have been of interest since Darwin's famous reflections on the subject. Here …

Compared to loose cultures, tight cultures are characterized by stronger norm adherence
and sanctioning of norm deviant behavior. In the current research, we proposed that culture …

In most anthropoid primates, the maxillary canine, mandibular canine, and mesial
mandibular premolar form a functional complex that hones the canines. Characters in …

Quantitative genetic analyses can indicate how complex traits respond to natural selection
by demonstrating the genetic relationships between features that constrain their evolution …

Male armaments are hypothesized to have evolved under intrasexual selection. Such traits
may function as signals, weapons, or both, in male–male mating competition. Primate …

Objectives To assess manifestations of metabolic bone disease (MBD) and their potential
environmental and phenotypic factors in captive and non‐captive baboon (Papio spp.) …

Objectives Reproductive skew is proposed to link to despotism in dominance hierarchies.
While studies illustrating male skew are plentiful, demonstrating the link to despotism is rare …

Males living in multi-male groups display a wide range of relationships with co-resident
