SEXUAL ISOLATION EVOLVES FASTER THAN HYBRID INVIABILITY IN A DIVERSE AND SEXUALLY DIMORPHIC GENUS OF FISH (PERCIDAE: ETHEOSTOMA)

Theory predicts that sexual (or behavioral) isolation will be the first form of reproductive isolation to evolve in lineages characterized by sexual selection. Here I directly compare the rate of evolution of sexual isolation with that of hybrid inviability in a diverse and sexually dimorphic genus...
