# What was Fisher's fundamental theorem of natural selection and what was it for?

Fisher's 'fundamental theorem of natural selection' is notoriously abstract, and, no less notoriously, many take it to be false. In this paper, I explicate the theorem, examine the role that it played in Fisher's general project for biology, and analyze why it was so very fundamental for Fisher. I defend and Lessard (1997) in the view that the theorem is in fact a true theorem if, as Fisher claimed, 'the terms employed' are 'used strictly as defined' (1930, p. 38). Finally, I explain the role… Expand

This paper provides a philosophical analysis of the ongoing controversy surrounding R.A. Fisher's famous ‘fundamental theorem’ of natural selection. The difference between the ‘traditional’ and… Expand

Fundamental Theorems of Evolution

- Biology, Medicine
- The American Naturalist
- 2017

It is suggested that the most fundamental theorem of evolution is the Price equation, both because of its simplicity and broad scope and because it can be used to derive four other familiar results that are similarly fundamental: Fisher’s average-excess equation, Robertson's secondary theorem of natural selection, the breeder's equation, and Fisher's fundamental theorem.

R.A. Fisher's gene‐centred view of evolution and the Fundamental Theorem of Natural Selection

- Mathematics, Medicine
- Biological reviews of the Cambridge Philosophical Society

The background to R.A. Fisher's enunciation of his Fundamental Theorem of Natural Selection in 1930 is traced and the Theorem in its original form explained. It can now be seen as the centrepiece of… Expand

The fundamental theorem of natural selection with mutations

- Mathematics, Medicine
- Journal of mathematical biology
- 2018

This paper builds a differential equations model from Fisher’s first principles with mutations added, and proves a revised theorem showing the rate of change in mean fitness is equal to genetic variance plus a mutational effects term, referred to as the fundamental theorem of natural selection with mutations.

Natural selection and the maximization of fitness

- Biology, Medicine
- Biological reviews of the Cambridge Philosophical Society

It may be a mistake to look for universal maximization principles justified by theory alone, but a more promising approach may be to find maximization Principles that apply conditionally and to show that the conditions were satisfied in the evolution of particular traits. Expand

"Describing our whole experience": the statistical philosophies of W. F. R. Weldon and Karl Pearson.

- 2011

This work argues for two related theses in light of a reading of several sources in which Weldon, independently of Pearson, reflects on his own motivations, and has here a counterexample to the claim that divergence in motivation will lead to a corresponding separation in methodology. Expand
