summaryNatural selection, random mutations, and evolutionary gradualism are pair-wise logically independent. Darwin seems to have thought that the first two provide an argument for the third, but it was R.A. Fisher, in his famous “geometrical argument,” who tried to demonstrate their mathematical connection. Kimura recognized that Fisher’s argument failed. Allen Orr has shown how the connection can be established by thinking about a sequence of mutations, rather a single mutation. In this talk I will try to present this history in a way that I hope will be accessible and conceptually interesting.
