The mammals are perhaps the most interesting of all the animals because of the intricacy and flexibility of their behaviour. There is an outstanding diversity in mammalian adaptions to life on land, in the sea and in the air. We have much to learn about and from the mammals. Indeed, when studying them we are looking at our fellow creatures. This book is the story of how and why mammals became the way they are, and why they behave the way they do. Macdonald begins by explaining evolution and adaption: how and why the mammals survived while the dinosaurs did not and how they have become so successful a form of life on earth. Citing many examples he describes feeding, communication and social behaviour.
