Sara L. Loo, Danya Rose, Michael Weight +2
The question of why males invest more into competition than offspring care is an age-old problem in evolutionary biology. On one hand, paternal care could increase the fraction of…
Modelling the evolution of traits in a two-sex population, with an application to grandmothering
M. H. Chan, K. Hawkes, P. S. Kim
We present a mathematical simplification for the evolutionary dynamics of a heritable trait within a two-sex population. This trait is assumed to control the timing of sex-specific…
Why does women's fertility end in mid-life? Grandmothering and age at last birth
Peter S. Kim, John S. McQueen, Kristen Hawkes
Great apes, the other living members of our hominid family, become decrepit before the age of forty and rarely outlive their fertile years. In contrast, women - even in high mortal…
Evolution of longevity, age at last birth and sexual conflict with grandmothering
Matthew H. Chan, Kristen Hawkes, Peter S. Kim
We use a two-sex partial differential equation (PDE) model based on the Grandmother Hypothesis. We build on an earlier model by Kim et al. [27] by allowing for evolution in both lo…
