Quick Summary

Sexual display refers to ritualized behaviors animals use to communicate specific information, primarily to members of their own species, for reproductive purposes. These displays can involve visual signals, sounds, smells, or touch. They often evolve from existing behaviors, such as food-giving, which become specialized for communication.1

Charles Darwin's theory of sexual selection explains these displays. It posits that traits enhancing an animal's ability to attract mates, even if they pose risks like increased visibility to predators, can evolve if they lead to greater reproductive success. This can involve males competing for females (intrasexual selection) or females preferring males with certain traits (epigamic selection). Displays can signal an individual's fitness, influencing mate choice and intensifying these signals over time.23
