When choosing a mate, females of different subspecies of Drosophila mojavensis recognize the right mating partners either mainly by their song or by their smell. New species apparently evolve when the chemical mating signal is altered and when, in turn, the signal is reinterpreted by the opposite sex in the context of other signals, such as the courtship song.
