Sexual dimorphism is the condition where the males and females of the same species exhibit distinct differences in morphology, behavior, or size. These observable distinctions can manifest in various ways, such as differences in coloration, size disparity, specialized ornamentation, or distinct display rituals. The evolution of such differences is generally attributed to various selective pressures, often involving reproductive isolation or differential selection for mate attraction or resource defense. Unlike systematic variations, which describe differences between species, sexual dimorphism refers exclusively to the variation within a single species, offering a key area of study in understanding evolutionary divergence and ecological interaction within biological populations.
