The Genetical Theory of Natural Selection: A Complete Variorum Edition

This is the definitive edition of R.A. Fisher's classic work—probably the best known book in evolutionary biology after Darwin's Origin of Species. The book was the first attempt to assess and explain Darwin's evolutionary theories in terms of genetic evolution. Based on the original 1930 edition, the book incorporates the many changes Fisher made for the second edition as well as unpublished material taken from Fisher's own copy.
