'''Fisherian runaway''' is a mechanism by which [[sexual selection]] leads to exaggerated physical or behavioral traits (ornamentation), sometimes to the extent of [[maladaptiveness]] and reduced population viability,<ref>Encyclopedia of Ecology, By Brian D.

'''Fisherian runaway''' is a model of how [[sexual selection]] can lead to exaggerated physical or behavioral traits (ornamentation) and exaggerated sexual preferences for these traits.
The coupling of traits and preferences results in feedback loops that can potentially cause [[maladaptive]] adaptations, reduced population viability,<ref>Encyclopedia of Ecology, By Brian D. Fath, page 316 https://books.google.com/books?hl=en&lr=&id=x1h7DwAAQBAJ&oi=fnd&pg=PA310&dq=%22fisherian+runaway%22+extinction+%22selection%22&ots=cq04BIA2Lf&sig=Otp5RbC3B_5W1ZR7Q3zGjPOe7uA#v=onepage&q=fisherian%20runaway&f</ref> and even extinction.<ref>The evolution of sexual strategy in modern humans: an interdisciplinary approach by Collins, Kendra Marie, https://studyres.com/doc/2550939/--california-state-university</ref><ref name="moen1999">Moen et al., 1999 http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.525.2990&rep=rep1&type=pdf</ref>
The name derives from the originator of the concept, Ronald Fisher, the 20th century British statistician, geneticist, eugenicist and racialist.
