Fisher's fundamental theorem of natural selection is an idea about genetic variance [1] [2] in population genetics developed by the statistician and evolutionary biologist Ronald Fisher. The proper way of applying the abstract mathematics of the theorem to actual biology has been a matter of some debate, however, it is a true theorem.
The Genetical Theory of Natural Selection is a book by Ronald Fisher which combines Mendelian genetics with Charles Darwin's theory of natural selection, [1] with Fisher being the first to argue that "Mendelism therefore validates Darwinism" [2] and stating with regard to mutations that "The vast majority of large mutations are deleterious; small mutations are both far more frequent and more ...
Ronald Fisher. Sir Ronald Aylmer Fisher FRS [5] (17 February 1890 – 29 July 1962) was a British polymath who was active as a mathematician, statistician, biologist, geneticist, and academic. [6][7] For his work in statistics, he has been described as "a genius who almost single-handedly created the foundations for modern statistical science ...
European pied flycatcher Ronald Fisher in 1912. The sexy son hypothesis in evolutionary biology and sexual selection, proposed by Patrick J. Weatherhead and Raleigh J. Robertson of Queen's University in Kingston, Ontario in 1979, [1] states that a female's ideal mate choice among potential mates is one whose genes will produce males with the best chance of reproductive success.
Fisher's principle was outlined by Ronald Fisher in his 1930 book The Genetical Theory of Natural Selection [2] (but has been incorrectly attributed as original to Fisher [1]). Fisher couched his argument in terms of parental expenditure , and predicted that parental expenditure on both sexes should be equal.

The work of Fisher, Haldane and Wright founded the discipline of population genetics. This integrated natural selection with Mendelian genetics, which was the critical first step in developing a unified theory of how evolution worked. [4] [5] John Maynard Smith was Haldane's pupil, whilst W. D. Hamilton was
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. [1][2][3] An example is the colourful and elaborate peacock plumage compared to the ...
