WebFisher’s ‘fundamental theorem of natural selection’ is notoriously abstract, and, no less notori-ously, 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
