The theory of adaptive radiation predicts that evolutionary diversification occurs when alternative phenotypes confer fitness advantages to different subsets of the same species facing divergent natural selection. A widespread outcome of this process is the evolution of new species (speciation). When natural selection imposes antagonistic fitness effects between the sexes of the same population, adaptive radiation may instead result in the evolution of ecological sexual dimorphism by disruptive selection.
