Key Concepts

Intrasexual Competition

Intrasexual competition occurs when members of the same gender, often males, compete directly for access to mates. This form of competition can lead to the evolution of traits like aggression or increased body size and is a driving force behind many adaptations related to mate acquisition.

Sexual Dimorphism

Sexual dimorphism refers to the differences in appearance between males and females of a species. These differences, which can include variations in size, coloration, or the presence of specialized structures, often arise as a result of sexual selection where traits that favor reproductive success are selectively enhanced in one sex.

Sexual Selection

Sexual selection is an evolutionary mechanism where certain traits become more common within a population because they increase an individual's chances of reproducing. This process often favors features that improve mating success rather than overall survival.
