Fisher's runaway
Fisherian runaway or runaway selection is a sexual selection mechanism proposed by the mathematical biologist Ronald Fisher in the early 20th century, to account for the evolution of ostentatious male ornamentation by persistent, directional female choice.

WebFisherian Runaway hypothesizes that preexisting sexual preference creates a positive feedback loop for preference of the trait. e.g. males with longer tails attract females and thus give them reproductive advantage. At the same time, the preference of the female for the longer tails increases their own advantage and thus creates a loop. solway smockWebAug 25, 2024 · Fisher’s runaway process has become a central theory to the investigation of the evolution and maintenance of mate choice and exaggerated male traits.
