DOI: 10.1371/journal.pbio.3002059
Abstract: Predation plays a role in preventing the evolution of ever more complicated sexual displays, because such displays often increase an individual’s predation risk. Sexual selection theory, however, omits a key feature of predation in modeling… read more here.
