Evolution of foraging behaviour: Deep intra-generic genetic divergence between territorial and non-territorial southern African patellid limpets

摘要

Graphical abstractDisplay OmittedHighlights?Deep phylogenetic divergence was found between territorial and non-territorial limpets.?Both foraging types radiated contemporaneously in two different genera.?Non-territorial foraging is the ancestral trait.?Territoriality is the derived trait.?Territoriality arose independently in both genera.AbstractSouthern Africa is a biodiversity hotspot of patellid limpets, with three genera (Helcion, CymbulaandScutellastra) iden
