sexual signal theory

Sexual signal theory suggests that animals, including humans, develop specific traits or behaviors that attract mates and indicate their reproductive fitness. These signals—such as bright colors, elaborate displays, or certain behaviors—serve to demonstrate qualities like health, strength, or genetic advantage. By showcasing these traits, individuals increase their chances of attracting a partner and reproducing successfully. The theory highlights how these signals evolved because they offer reliable information about an organism’s suitability as a mate, influencing mate choice and reproductive success in various species.
