Significance How sexual features and preferences originate evolve is one of the most important contentious problems in evolutionary biology. In some species, females choose male traits that indicate genetic quality or confer benefits. Thus, female are assumed to at same time coevolve. contrast, sensory exploitation occurs when males take advantage females’ preexisting biases. We show Drosophila by other through use a pheromone gain advantage. Notably, leads adaptation. These findings provide mechanism for origins previously unidentified example between males.
