The availability of molecular data has fundamentally changed the field of evolutionary biology over the past 20 years. Molecular evolution and molecular ecology are now independent scientific fields, and molecular markers are used in every corner of evolutionary biology from phylogenetics to conservation biology. As these fields became more oriented toward molecular data, the need for new methods for analyzing such data arose. Most of these methods are based on coalescent theory, the topic of a new book, Gene Genealogies, Variation and Evolution, by J. Hein, M. H. Schierup and C. Wiuf. Coalescent theory provides a bridge between population genetic models and molecular data. It describes how demography, recombination, and other factors affect the shape of gene trees and provides tools for making statistical inferences from molecular population genetic data. Coalescent theory is necessary in phylogenetics to understand why gene trees may differ from species trees, in conservation biology to understand the relationship between effective population size and census population size, and in molecular ecology to understand almost anything at all. Acquiring a basic knowledge of coalescent theory should be a great help to any evolutionary biologist, and it is a must for researchers and students in population genetics or molecular ecology. Unfortunately, the voluminous literature on coalescent theory has been largely inaccessible to biologists. Hudson’s (1990) seminal review has been the most commonly used introduction, but today it is neither comprehensive enough nor is it up to date. There has been a dire need for a good book introducing coalescent theory to biologists. Gene Genealogies, Variation and Evolution fills this important gap. It provides a basic introduction to coalescent theory and goes in depth with many topics including the effect of recombination and linkage disequilibrium (LD). As is the case with most scholarly books, Gene Genealogies, Variation and Evolution provides most focus on the areas in which the authors have made most of their research contributions. In this case, that is a good thing, because the authors have been involved in a diverse array of very exciting research. After the first two introductory chapters, the book covers some more advanced material in a chapter on tree topologies. Thereafter follow two chapters on the effects of various demographic models, selection, and recombination. The next chapter briefly outlines methods for making inferences from data using coalescent theory, and the two last chapters of the book cover more specialized material on LD mapping and human evolution. Focusing on these two spe-
