Abstract: | The diverse characteristics among closely related species are often involved in communication between the sexes. The traditional view that intersexual communication behaviors evolve in a complementary way is called into question by the sensory exploitation hypothesis. By predicting a lack of coordinated evolution between signals and preferences, the sensory exploitation hypothesis is distinct from other mechanisms of sexual selection. Tests of sensory exploitation have taken a multi-disciplinary approach, with insights from sensory physiology, behavior and phylogenetic comparisons. By demonstrating that signals and receivers are not closely coupled, and that signal preference pre-dates signal origin, proponents of the model argue that sensory exploitation is an evolutionary force responsible for the diversification of intersexual communication signals. |
