In what way can sexual selection lead to evolutionary change?

Sexual selection can lead to evolutionary change primarily through the development of traits that improve mating success. This process occurs when certain individuals possess advantageous traits that make them more attractive to potential mates. Examples of such traits include vibrant colors, elaborate courtship displays, or more pronounced physical features. These traits can increase an individual's chances of reproduction, allowing them to pass on their genes to the next generation.

Over time, as these favored traits become more common within the population, they can lead to significant changes in the species. This mechanism highlights the role of mate choice and competition in shaping evolutionary pathways, emphasizing that reproductive success, rather than survival alone, can drive the evolution of particular characteristics. Sexual selection thus acts as a powerful force in shaping animal behavior and morphology, contributing to the diversity of life we see today.
