Sexual selection is the
theory proposed by
Charles Darwin that states that the frequency of
traits can increase or decrease depending on the attractiveness of the bearer.
Biologists today distinguish between "male to male combat" (it is usually males who fight), "mate choice" (usually female choice of male mates) and "mate coercion" (forced mating). Traits selected for by male combat are called "weapons", and traits selected by mate choice are called "ornaments". Much attention has recently been given to
cryptic female choice,
[1] a phenomenon in internally fertilising animals such as mammals and birds, where a female will get rid of a male's
sperm without his knowledge. The equivalent in male-to-male combat is
sperm competition.
The exact effect of sexual selection depends on the
sex ratio, which is usually slightly
biased in favour of the "limiting" sex (typically females).
Male to male combat is also classified as
intrasexual competition, while mate choice and mate coercion are also known as
intersexual competition.
Females often prefer to mate with males with external ornaments - exaggerated features of morphology. These can plausibly arise because an arbitrary female preference for some aspect of male morphology initially increased by
genetic drift, creating, in due course, selection for males with the appropriate ornament. This is known as the
sexy son hypothesis. Alternatively, genes that enable males to develop great ornaments may simply show off greater
disease resistance or a more efficient
metabolism - features that also benefit females. This idea is known as the
good genes hypothesis.
