This study shows that group size affects kinship dynamics and age-related social behaviors in social mammals, with smaller groups promoting more extreme helping/harming behaviors, especially in younger individuals.

This study extends kinship dynamics models to include age-linked changes in survival and fecundity, showing improved predictions of female kinship dynamics in killer whales across life stages.

The paper critiques a previous study claiming menopause is widespread in mammals, showing its methodology is flawed and concluding menopause is rare.
