Nei and Kumar's "Molecular Evolution and Phylogenetics" is basically an updated version of Nei's 1987 "Molecular Evolutionary Genetics" book. Accordingly, attention is shifted to reviewing many recent advances in methods of phylogenetic inference with an obvious bias towards distance methods, particularly those which the senior author devised. In fairness, they give decent coverage to the more popular parsimony and likelihood methods as well. The great strength of the book is the number of real examples used to illustrate properties of the methods, and their focus on statistical methodology without miring the reader in detailed mathematics. The disappointment is that while breadth of coverage is tolerable, depth is lacking. Expanding their views on the shortcomings of likelihood in choosing tree topology and likelihood ratio-tests in choosing models of sequence evolution would have been most enlightening, particularly as these issues have been brushed lightly aside by phylo-likelihoodists. Other methods (Hadamard transformations, Bayesian phylogenetic inference) were absent altogether. Further the chapter on molecular clocks was disappointing--old 1980s controversies were rehashed, while there was nothing on methods that relax the assumption of rate constancy while still allowing divergences to be dated. Admittedly some of this is very new and research is ongoing, but there isn't even a hint of these developments in this chapter. Another plus though is the addition of a chapter on inferring ancestral states of molecular sequences.
Unlike Molecular Evolutionary Genetics, far too little of the book is devoted to methods at the population level, and what is there again smacks of state-of-the-art 15-20 years ago. I was hoping for much more coverage of microsatellite and AFLP data. There was very little for either, while now rarely-used RFLPs were given extensive coverage.
In short, this book was too short, particularly for the price, and I almost gave it 3 stars rather than 4. However, if you are a phylogeneticist, you will probably want to have this book on your shelf. A lighter introduction for the uninitiated would be Rod Page's "Molecular Evolution" or Graur and Li's "Fundamentals of Molecular Evolution". However, my hopes for a good comprehensive text and reference on phylogenetic methods now rest on publication of Joseph Felsenstein's "Inferring Phylogenies".
