Webrunaway hypothesis A hypothesis proposed by R. A.Fisher in 1930 to explain the consequences of female selection of a particular male trait (e.g. the length of the tail in a bird).

Here, we correct Fisher's model and show that it contains all the ingredients of a working runaway process. We derive quantitative predictions of his model using numerical techniques that were unavailable in Fisher's time.
