It is one of two components of sexual selection (the other is male-male competition or intersexual selection). Darwin first introduced his ideas on sexual selection in 1871 but advances in genetic and molecular techniques have led to major progress in this field recently.
Five mechanisms that explain the evolution of mate choice are currently recognized. They are direct phenotypic benefits, sensory bias, Fisherman runaway, indicator traits, and genetic compatibility. These mechanisms can co-occur and there are many examples of each.
In systems where mate choice exists, one sex is competitive with same-sex members and the other sex is choosy (selective when it comes to picking individuals to mate with). In most species, females are the choosy sex that discriminates amongst competitive males but there are several examples of reversed roles. There is an example: Charles Darwin first expressed his ideas on sexual selection and mate choice in his book The Descent of Man, and Selection in Relation to Sex in 1871. He was perplexed by the elaborate ornamentation that males of some species have because they appeared to be detrimental to survival and have negative consequences for reproductive success. He proposed two explanations for the existence of such traits: these traits are useful in male-male combat or they are preferred by females.
