## Analysis of variance

Collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among means.

ANOVA was developed by the statistician Ronald Fisher.

## Modern synthesis (20th century)

The early 20th-century synthesis reconciling Charles Darwin's theory of evolution and Gregor Mendel's ideas on heredity in a joint mathematical framework.

An early event in the modern synthesis was R. A. Fisher's 1918 paper on mathematical population genetics, but William Bateson, and separately Udny Yule, were already starting to show how Mendelian genetics could work in evolution in 1902.

## Population genetics

Subfield of genetics that deals with genetic differences within and between populations, and is a part of evolutionary biology.

Its primary founders were Sewall Wright, J. B. S. Haldane and Ronald Fisher, who also laid the foundations for the related discipline of quantitative genetics.

## Rothamsted Research

One of the oldest agricultural research institutions in the world, having been founded in 1843.

In 1919 Russell hired Ronald Fisher to investigate the possibility of analysing the vast amount of data accumulated from the "Classical Field Experiments."

## Sexual selection

Mode of natural selection in which members of one biological sex choose mates of the other sex to mate with , and compete with members of the same sex for access to members of the opposite sex (intrasexual selection).

The theory was given a mathematical basis by Ronald Fisher in the early 20th century.

## Sewall Wright

American geneticist known for his influential work on evolutionary theory and also for his work on path analysis.

He was a founder of population genetics alongside Ronald Fisher and J. B. S. Haldane, which was a major step in the development of the modern synthesis combining genetics with evolution.

## Biostatistics

Biostatistics (also known as biometry) are the development and application of statistical methods to a wide range of topics in biology.

Ronald Fisher developed several basic statistical methods in support of his work studying the crop experiments at Rothamsted Research, including in his books Statistical Methods for Research Workers (1925) end The Genetical Theory of Natural Selection (1930). He gave many contributions to genetics and statistics. Some of them include the ANOVA, p-value concepts, Fisher's exact test and Fisher's equation for population dynamics. He is credited for the sentence “Natural selection is a mechanism for generating an exceedingly high degree of improbability”.

## Mate choice

One of the primary mechanisms under which evolution can occur.

Ideas on sexual selection were first introduced in 1871, by Charles Darwin, then expanded on by Ronald Fisher in 1915.

## Statistics

Discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Ronald Fisher coined the term null hypothesis during the Lady tasting tea experiment, which "is never proved or established, but is possibly disproved, in the course of experimentation".

## Mendelian inheritance

Type of biological inheritance that follows the principles originally proposed by Gregor Mendel in 1865 and 1866, re-discovered in 1900 by Hugo de Vries and Carl Correns, and popularized by William Bateson.

Ronald Fisher combined these ideas with the theory of natural selection in his 1930 book The Genetical Theory of Natural Selection, putting evolution onto a mathematical footing and forming the basis for population genetics within the modern evolutionary synthesis.
