Mammal

Did you know that when two bull hippos yawn at each other, they aren't actually tired, but displaying territorial ownership?This book sets out to explore the world of the mammals - what they look like, their body structure, evolution, breeding, habits and behaviours, and in doing so it should hopefully cast some light on our place in their world.

This title is a comprehensive guide to the natural world of mammals.

It covers everything, from answering the question "what separates us from other groups of species - birds, fish, spiders and insects" to the evolution of mammals over the last 200 million years.
