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.

The paper develops a model to predict human kinship dynamics using marriage practices, residence rules, and demographic parameters, showing it captures patterns of male and female kinship dynamics across diverse societies.

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.
