This book provides the broadest and most balanced review of systematics that I have seen. Minnelli provides a clear and highly readable interpretation of developments in systematics, especially since the 1960s. Many authors have dealt with the same Writing on the subject has subject from a particular, and often extreme, standpoint. been more vitriolic than on most other topics in biology. Whilst Minelli leaves the reader in no doubt of his own views, he provides a careful dissection of the key issues that evolutionary systematists, pheneticists, cladists and others have debated. The great success of the book is that this approach is not directed towards ‘setting the record straight’ but rather at identifying the complex issues at the heart of systematics that make the discipline such an exciting and challenging subject. Minelli’s discussion of how the principle of parsimony is translated into practicality i.n terms of the choice of analytical procedures offered by the main computer programmes provides a good example of his approach and highlights the fact that this book will meet the needs of students and experienced researchers. The differences between the Fitch, Wagner, Dollo and Camin-Sokal parsimony methods are clearly 0024-4066/95/001107+04808.00/0
