Data from: Explaining sex differences in lifespan in terms of optimal energy allocation in the baboon

We provide a quantitative test of the hypothesis that sex role
specialisation may account for sex differences in lifespan in baboons if
such specialisation causes the dependency of fitness upon longevity, and
consequently the optimal resolution to an energetic trade-off between
somatic maintenance and other physiological functions, to differ between
males and females. We present a model in which females provide all
offspring care and males compete for access to reproductive females and in
which the partitioning of available energy between the competing
fitness-enhancing functions of growth, maintenance and reproduction is
modelled as a dynamic behavioural game, with the optimal decision for each
individual depending upon his/her state and the behaviour of other members
of the population. Our model replicates the sexual dimorphism in body size
and sex differences in longevity and reproductive scheduling seen in
natural populations of baboons. We show that this outcome is generally
robust to perturbations in model parameters, an important finding given
the same behaviour is seen across multiple populations and species in the
wild. This supports the idea that sex differences in longevity result from
differences in the value of somatic maintenance relative to other
fitness-enhancing functions in keeping with the disposable soma theory.
