* '''Sexual Selection''' — Selection for traits that increase an individual's mating success.
* '''Intrasexual Selection''' — Competition between members of the same sex (usually males) for access to mates (e.g., "Combat" or "Antlers").
* '''Intersexual Selection''' — When one sex (usually females) chooses a mate based on specific traits (e.g., "Choice" or "Beauty").
* '''Sexual Dimorphism''' — Distinct differences in appearance between males and females of the same species.
* '''The Handicap Principle''' — The idea that "Expensive" traits (like a heavy tail) are honest signals of quality because only a very healthy male could survive with them.
* '''Fisherian Runaway''' — A feedback loop where a female preference and a male trait evolve together until the trait becomes extreme.
* '''Good Genes Hypothesis''' — The theory that females choose traits that are "markers" for a strong immune system or overall health.
* '''Parental Investment''' — The time and energy a parent spends on an offspring at the cost of the parent's ability to invest in other offspring.
* '''Lek''' — An area where males gather to perform competitive displays to attract females.
* '''Nuptial Gift''' — A physical resource (like food) provided by a mate to increase their chances of mating.
* '''Sperm Competition''' — A form of post-mating competition where the sperm of different males compete to fertilize the same egg.
* '''Anisogamy''' — The condition of having gametes of different sizes (small, cheap sperm vs. large, expensive eggs).
