Field studies of natural mammal populations present powerful opportunities to investigate
the determinants of health and aging using fine-grained observations of known individuals …

Natural selection will favor male care when males have limited alternative mating
opportunities, can invest in their own offspring, and when care enhances males' fitness …

Adverse conditions in early life can have negative consequences for adult health and
survival in humans and other animals. What variables mediate the relationship between …

Social bonds enhance fitness in many group-living animals, generating interest in the
processes that create individual variation in sociality. Previous work on female baboons …

Adverse experiences during early life exert important effects on development, health,
reproduction, and social bonds, with consequences often persisting across generations. A …

Developmental plasticity facilitates energetically costly but potentially fitness‐enhancing
adjustments to phenotypic trajectories in response to environmental stressors, and thus may …

Early life experiences have a significant influence on adult health and aging processes in
humans. Despite widespread interest in the evolutionary roots of this phenomenon, very little …

Cohort effects, reflecting early adversity or advantage, have persisting consequences for
growth, reproductive onset, longevity, and lifetime reproductive success. In species with …

The early-life environment can profoundly shape the trajectory of an animal's life, even years
or decades later. One mechanism proposed to contribute to these early-life effects is DNA …

Birth, and the period shortly thereafter, is a perilous time for any organism. Following
parturition or hatching, individuals face many challenges, including environmental stressors …
