TL;DR: The utility of adaptive models proposed to explain developmental responses to early‐life adversity, particularly for long‐lived mammals such as humans, are evaluated and how parent‐offspring conflict complicates the authors' understanding of whether mothers or offspring benefit from these responses is highlighted.

TL;DR: These are the first data to demonstrate that specific males are associated with the onset of maturation in a wild primate and to provide a possible mechanism for this change, suggesting that all male-mediated maturation (whether accelerated, on-time, or delayed) may be governed by similar neuroendocrine processes.

TL;DR: In Nepal gray langurs, males received 3 times more injuries during the mating season, suggesting strong competition for mates during this period, and females experienced more injuries before conception, suggesting competition to meet the nutritional requirements for reproduction.

TL;DR: The costbenefit ratio of group living is thought to vary with group size: individuals in optimally sized groups should have higher fitness than individuals in groups that are either too large or too small as discussed by the authors.

TL;DR: In this article , the authors evaluated whether the more "classic" socioecological variables (i.e., maternal rank, group size) predict maturation age in wild geladas-a primate species with known male-mediated effects on maturation and a grassy diet that is not expected to generate intense female competition.
