conference paper description
Most attempts to answer the question of whether populations of groups can undergo natural selection focus on properties of the groups themselves rather than the dynamics of the population. Those approaches to group selection that do emphasize dynamics lack an account of the relevant notion of equivalent dynamics. I present a new approach to identifying instances of evolution by natural selection that is based upon dynamical symmetries. I apply the symmetry method to arrive at an affirmative but qualified answer to the question of group selection.
