In this excellent and concise book, the pre-eminent authors provide an overview of the 70 years of research on genetics and epigenetic phenomena and mechanisms in a model eukaryote,Paramecium. Given that Paramecium contains more than 40,000 genes, i.e. more than the human genome, this is a powerful model system to explore the interplay of genetic and epigenetic control in both growth and development. A resurgence of interest in the rather neglected field of epigenetics, spurred by interest in stem cells, makes this a particularly timely volume. Chapter 3 introduces the general morphology, reproduction and life cycle of Paramecium, which makes the book easy to read for those less familiar with ciliate biology. The format of the book with clearly defined chapters and subheadings in conjunction with well-presented tables, diagrams and a comprehensive index enables the reader to easily identify areas of interest. My only personal disappointment was that a few photographs were not perfectly presented. Nonetheless, I believe this book will be very useful for students and researchers alike.
