'''Fisherian runaway''' is a mechanism by which sexual selection leads to exaggerated, [[Maladaptiveness|maladaptive]] and unhealthy, physical traits (ornamentation) in some individuals of a species. Which plays a role in the evolution of [[beauty]]. The Fisherian runaway process can result in reduced population viability<ref>Encyclopedia of Ecology, By Brian D.
