Abstract

Evolutionary branching and diversification in interactions with continuous behavioral traits is important for understanding the emergence of distinct, discrete, and coexisting strategies. In social dilemmas, this suggests an evolutionary pathway for the origin of cooperators and defectors. Here we study evolutionary diversification in structured populations and identify mechanisms driving spontaneous and persistent diversification. Through analytical and numerical techniques, we demonstrate that spatial structure admits new modes of diversification that complement classical evolutionary branching. In particular, when selection is strong, diversification tends to occur more readily than in unstructured populations.
