Group selection models combine selection pressure at the individual level with selection pressure at the group level … with disproportionately many other cooperators, cooperation can evolve. The existing literature on group selection …

fitness. Although there are interesting classes of group selection models for which this is possible, we show that it is not … true in general. With a simple set of group selection models, we show two distinct limitations that prevent recasting in … relatedness of its meaning. The second limitation is across time. We show that one can find the trajectory for the group selection …

This paper introduces two new concepts in evolutionary game theory: Nash equilibrium with Group Selection (NEGS) and … Evolutionarily Stable Strategy with Group Selection (ESSGS). These concepts generalize Maynard Smith and Price (1973) to settings …. NEGS and ESSGS are to the canonical group selection model of evolutionary theory what Nash Equilibrium and ESS are to the …

group selection model can be recast in terms of inclusive fitness. Although there are interesting classes of group selection … models for which this is possible, we show that it is not true in general. With a simple set of group selection models, we … show that one can find the trajectory for the group selection model by solving a partial differential equation, and that it …

A widespread claim in evolutionary theory is that every group selection model can be recast in terms of inclusive … fitness. Although there are interesting classes of group selection models for which this is possible, we show that it is not … true in general. With a simple set of group selection models, we show two distinct limitations that prevent recasting in …
