What are species? What are the factors involved in their evolution? Dr Max King presents an up-to-date synthesis of theoretical, experimental and descriptive perspectives on speciation in higher organisms. The book provides a fresh insight into the processes involved in speciation utilizing the multi-dimensional databases now available. The author clearly and concisely analyses the most recent research in plant and animal populations, concentrating on the evolutionary processes, the role of chromosomes and the genetic mechanisms involved in speciation. This book will be essential reading for research workers in genetics, evolutionary studies, botany and zoology, as well as being of interest to advanced students entering the field.

CHOICE Review

The major argument of this work is revealed in the subtitle. King expands the case that speciation by chromosomal rearrangement and modification is (one of) the most important modes of species origination. Thus, the main title is rather misleading, as other aspects of species evolution and origin are given short shrift. The early chapters present a good if brief review of alternative modern species concepts and the meaning of genetic differentiation during allopatric speciation. A discussion of founder-effect speciation leads into chapters on chromosomal rearrangements and their fixation through isolation, hybridity, genetic versus chromosomal change and speciation, and the role of molecular mechanisms. A final chapter reviews the foregoing and discusses a variety of special problems, such as the relationship between morphological and chromosomal change and the idea that punctuated equilibrium might be driven by chromosomal speciation. The author demonstrates the reality of chromosomal factors in speciation, but may put too much weight on this mode: it is doubtful that most evolutionists would count chromosomal speciation as one of only two modes, combining as does King all other models as "genic." Probably too complex for undergraduates; nonetheless, an important book for graduate students and researchers. E. Delson; Herbert H. Lehman College, CUNY
