Handicap Principle

The Handicap Principle is a theory in evolution that suggests certain traits or behaviors can be disadvantageous yet signal strength or fitness. For example, a peacock's extravagant tail makes it more visible to predators, but it also attracts mates. This idea posits that only the strongest individuals can afford to develop and maintain such costly traits, thus signaling their genetic quality. In essence, by displaying these "handicaps," animals communicate their health and vitality, making them more appealing to potential partners, ensuring their genes are passed on.
