This book questions some contemporary trends in biology. The author's starting point is the relationship between individual animals, rather than the individual animals themselves, and in this book he explores where this path leads, showing why play is so deeply a part of mammalian behaviour.
`Involves a rethinking of basic biological assumptions about the origin and nature of play, with deep significance for our understanding of ourselves and our relationships with the animal kingdom...Original, well-grounded in observation, and controversial.' - Brian Goodwin, Schumacher College.
