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’ andExpand
Fundamental Theorems of Evolution

  • 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.

  • 2014
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 ofExpand
The fundamental theorem of natural selection with mutations
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.

Is there some reorientation for the expression of natural selection that may provide subtle perspective, from which we can understand our subject more deeply and analyze our problems with greaterExpand
Natural selection and the maximization of fitness
  • Jonathan Birch
  • Biology, Medicine
  • Biological reviews of the Cambridge Philosophical Society
  • 2016
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
Evolution and Directionality: Lessons from Fisher’s Fundamental Theorem
As is well-known, the second law of thermodynamics has the property of being ‘time asymmetric’, unlike for example the laws of Newtonian mechanics, which are time reversal-invariant. The second lawExpand

There is a 'Neo-Paleyan' tradition in British evolutionary theorising, which began with Darwin and continues to the present day. This tradition conceives of adaptation in terms of design, and itExpand
Neo-Darwinism and Evo-Devo: An Argument for Theoretical Pluralism in Evolutionary Biology
There is an ongoing debate over the relationship between so-called neo-Darwinism and evolutionary developmental biology (evo-devo) that is motivated in part by the possibility of a theoreticalExpand
"Describing our whole experience": the statistical philosophies of W. F. R. Weldon and Karl Pearson.
  • Charles H. Pence
  • Philosophy, Medicine
  • Studies in history and philosophy of biological and biomedical sciences
  • 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


An interpretation and proof of the Fundamental Theorem of Natural Selection.

An interpretation of the Fundamental Theorem of Natural Selection implies that it is correct as a mathematical statement, but of less biological value than was claimed by Fisher. Expand
Metaphysics and population genetics: Karl Pearson and the background to Fisher's multi-factorial theory of inheritance

On the change of population fitness by natural selection2 3
A general equation for the role of additive, dominance, and epistatic components of fitness in determining the rate of change in population fitness is given and claims that this law should hold the same position among the biological sciences as the second law of thermodynamics in physical sciences.
