Lecture 13 - Sexual Selection

This video was recorded at EEB 122 - Principles of Evolution, Ecology and Behavior. Sexual selection is a component of natural selection in which mating success is traded for survival. Natural selection is not necessarily survival of the fittest, but reproduction of the fittest. Sexual dimorphism is a product of sexual selection. In intersexual selection, a sex chooses a mate. In intrasexual selection, individuals of one sex compete among themselves for access to mates. Often honest, costly signals are used to help the sex that chooses make decisions. Reading assignment: Stearns, Stephen C. and Rolf Hoekstra. Evolution: An Introduction, chapter 11
