Social nonhuman animals are powerful models for studying underlying factors related to
lifelong health outcomes following early life adversities (ELAs). ELAs can be linked to …

Social experiences are strongly associated with individuals' health, aging, and survival in
many mammalian taxa, including humans. Despite their role as models of many other …

Discerning the relationship between sociality and longevity would permit a deeper
understanding of how animal life history evolved. Here, we perform a phylogenetic …

Evolutionary explanations for mammalian sociality typically center on inclusive-fitness
benefits of associating and cooperating with close kin, or close maternal kin as in some …

The extent of (in) equality is highly diverse across species of social mammals, but we have a
poor understanding of the factors that produce or inhibit equitable social organizations …

Help is directed towards kin in many cooperative species, but its nature and intensity can
vary by context. Humans are one of few species in which grandmothers invest in …

Understanding how and why menopause has evolved is a long-standing challenge across
disciplines. Females can typically maximize their reproductive success by reproducing for …

Recovering small, endangered populations is challenging, especially if the drivers of
declines are not well understood. While infrequent births and deaths may be important to the …

Age-related changes in the patterns of local relatedness (kinship dynamics) can be a
significant selective force shaping the evolution of life history and social behaviour. In …

In classical evolutionary models, the force of natural selection diminishes with age toward
zero by last reproduction. However, intergenerational resource transfers and other late-life …
