Biological sciences: Geographical uniformity of selectively neutral polymorphisms

Abstract

IN a recent issue of Nature, Bulmer1 criticised the ‘neutral theory’2 of protein polymorphisms on the ground that the infinite neutral allele hypothesis of Kimura and Crow3, when combined with Malécot's two-dimensional dispersal model4,5 leads to results which do not fit to actual data6–8. In this note, we intend to show that Bulmer's conclusions are entirely due to the unwarranted assumption of infinite population size inherent in Malécot's formulation, and that when the assumption is corrected, the data in fact are consistent with the neutral theory.
