## What is Fisher’s fundamental theorem of natural selection? |

Evolutionary biologist, geneticist, and statistician Sir Ronald Aylmer Fisher (1890–1962) first proposed Fisher’s fundamental theorem of natural selection in 1930. A mathematical concept, it states that the rate of evolutionary change in a population is proportional to the amount of genetic diversity available. He is also often credited with creating the foundations for modern statistical science.
