Caption: Female túngara frogs have a limited cognitive ability to recognize increasing elaboration in male mating calls. Fringe-lipped bats that hunt the singing males also have a limited cognitive ability to notice increases in male call complexity. So, the evolution of increasing complexity in male calls is limited by decreased female response rather than increased predation.
