John Stevens Henslow is known for his formative influence on Charles Darwin, who described their meeting as the one circumstance "which influenced my career more than any other." A Professor of Botany at Cambridge University, Henslow was Darwin's teacher and eventual life-long friend, but what of the man himself? In this new biography, much previously unpublished material has been carefully gathered to produce a rounded picture of a remarkable academic and Victorian philanthropist. The time in 1829-31, when Darwin "walked with Henslow" in and around Cambridge, was followed directly by Darwin's voyage around the world. The gradually changing relationship between teacher and pupil over the course of time is revealed through their correspondence, illuminating a remarkable friendship that persisted, in spite of Darwin's eventual atheism and Henslow's never-failing liberal Christian belief, to the end of Henslow's life.

What regularities lie behind the development and organization of behaviour in animals and humans? One theme emerging from this book is that ideas have to flow in both directions between the different levels of analysis - between the neural and behavioural levels and between the individual and the social group. Another theme is that it is not enough to identify the many factors operating in the development and integration of behaviour. The processes must also be studied directly. Bringing together work at different levels and studying behavioural dynamics require more knowledge and expertise than any one person can usually command. Links have to be made between different disciplines and specialists have to learn to work with others who speak with what at first seem to be mutually incomprehensible scientific languages. The book illustrates how this may be achieved. The themes of this book are strongly related to the approach of Robert Hinde, in whose honour the chapters were written.

How do we understand and explain the apparent dichotomy between plasticity and robustness in the context of development? Can we identify these complex processes without resorting to 'either/or' solutions? Written by two leaders in the field, this is the first book to fully unravel the complexity of the subject, explaining that the epigenetic processes generating plasticity and robustness are in fact deeply intertwined. It identifies the different mechanisms that generate robustness and the various forms of plasticity, before considering the functional significance of the integrated mechanisms and how the component processes might have evolved. Finally, it highlights the ways in which epigenetic mechanisms could be instrumental in driving evolutionary change. Essential reading for biologists and psychologists interested in epigenetics and evolution, this book is also a valuable resource for biological anthropologists, sociobiologists, child psychologists and paediatricians.

The most commonly kept domestic animal in the developed world, the cat has been a part of human life for thousands of years. Cats have been both worshipped and persecuted over this long period - either loved or hated for their enigmatic self-reliance and the subject of numerous myths and fables. Highlighting startling discoveries made over the last ten years, this new edition features contributions from experts in a wide range of fields, providing authoritative accounts of the behaviour of cats and how they interact with people. Thoroughly revised and updated to include information on the basic features of cat development and social life, the history of their relations with humans, health and welfare problems, and the breeding of cats for sale and for show. It is intended for all those, whether specialist or general reader, who love or are simply intrigued by these fascinating animals.

Twenty-one specially-commissioned articles provide a clear picture of the current state of thinking about mate choice. Brings together modern thinking on the various functions of mate choice and its role in evolution.

What role does playful behaviour and playful thought take in animal and human development? How does play relate to creativity and, in turn, to innovation? Unravelling the different meanings of 'play', this book focuses on non-aggressive playful play. The authors emphasise its significance for development and evolution, before examining the importance of playfulness in creativity. This discussion sheds new light on the links between creativity and innovation, distinguishing between the generation of novel behaviour and ideas on the one hand, and the implementation of these novelties on the other. The authors then turn to the role of play in the development of the child and to parallels between play, humour and dreaming, along with the altered states of consciousness generated by some psychoactive drugs. A final chapter looks forward to future research and to what remains to be discovered in this fascinating and important field.
