Reviews

The book is valuable as a condensed version of the huge amount of fine work the authors have done on the finches. It should be accessible to scientists and informed lay audiences alike. The theory and ecological aspects are very compelling. -- Robert M. Zink, Bioscience

One of the most compelling documentations of the operation of natural selection. In this book, the Grants aim to capture the key insights provided by Darwin's finches into mechanisms of adaptation and speciation generally. They succeed in making a complex topic accessible without losing the excitement inherent in tackling a difficult problem. There is enough depth to stimulate serious students of evolutionary biology, enough explanation for general readers and an approachable style that will please both. -- Roger Butlin, Times Higher Education This Princeton-based couple presents their own accessible summary of their life's research in How and Why Species Multiply. The authors explain the scientific hypotheses involved...with admirable clarity...yet the book's real strength is not theory but data. The Grants' account makes exciting and lucid reading. Among those who should take note are doubters of 'old-fashioned' research methods who marvel at the prospects of genomics in the lab and wonder what use bird bands have in modern science. -- Hanna Kokko, Science Distilled into 200 pages, this is the life's work of two of evolutionary biology's greatest advocates, Peter and Rosemary Grant. In this book they meld insights from geography, behaviour, ecology and genetics to paint a complex but compelling picture of the evolutionary process. [A] must-have primer for any biology student. -- Henry Nicholls, New Scientist The authors' assertion that 'speciation is a process and not an event,' comes across clearly in this concise and accessible tale of 3 million years of finch evolution. -- Science News The book illustrates how laboratory work, particularly in developmental biology and molecular genetics, can be combined effectively with observations and experimental work in the field. -- J. S. Schwartz, emeritus, CUNY College of Staten Island, for CHOICE This book presents a succinct and most readable summary of one of the most important contemporary field experiments in evolution and adaptive radiation. It should be basic reading for any biologist. -- Ghillean Prance, Biologist [T]he book is authoritative, well prepared and edited ... and attractive. The Grants have provide and excellent third part for the Darwin's finch trilogy, and this volume should serve admirably as a summary of the knowledge that they have accumulated. -- A. Townsend Peterson, Quarterly Review of Biology How and Why Species Multiply is so impressive and such a stimulating read for two primary reasons, the first being the data presented throughout the work. Rarely do we have such detailed data on any natural system and the book draws great strength from this. The second reason is the commanding role given to ecological interactions in explaining the evolutionary dynamics of Darwin's finches. -- Utku Perktas, Ibis The book is valuable as a condensed version of the huge amount of fine work the authors have done on the finches. It should be accessible to scientists and informed lay audiences alike. The theory and ecological aspects are very compelling. -- Robert M. Zink, Bioscience

Author Information

Peter R. Grant and B. Rosemary Grant are professors emeriti at Princeton University. In recognition of their decades of work studying the ecology, behavior, genetics, and evolution of Darwin's finches, they were awarded the 2005 Balzan Prize and the 2009 Kyoto Prize.
