Slatkin and Veuille invite leading population geneticists to summarise many of the recent developments in population genetics theory and its application to genetic data. The book has been assembled in honour of the late Gustave Malecot, one of the pioneers of theoretical population genetics.Whilst early chapters summarise Malecot's life and scientific contributions, the rest of the book is devoted to topics that trace their origin in Malecot's work. Several of the contributions describe recent developments in the coalescent theory, which can be viewed as a generalisation of Malecot'smethod for analysing identity by descent. Other chapters discuss recent developments in the study of geographic variation, genetic linkage, and allele age. The diversity of topics and the effectiveness with which various theoretical methods can be applied to DNA sequence data illustrates both theincreasing relevance of theoretical population genetics and the depth of Malecot's insight into fundamental genetic processes. This exciting work will be of interest to population and statistical geneticists as well as a wider audience of evolutionary biologists.
