Females may chose males based on the resources they provide or the genetic benefits for their offspring. There is often sexual conflict and this continues after mating sperm competition and female choice of sperm. Chapter 8 reviews parental care across the animal kingdom, and three inter-related conflicts: between male and female parent over who should care, and how much care to provide; between siblings; and between parents and their offspring.

In Chapter 9, we show how different mating systems emerge depending on the economics of parental care and mate defence. The use of DNA profiles to measure parentage has now become routine and has revolutionised our view of family life, revealing for example that social monogamy does not necessarily mean genetic monogamy.

Chapter 10 examines sex allocation: the problem of how a parent should divide its investment between male and female offspring. Sex allocation in hymenopteran insects provides some of the most convincing quantitative tests of evolutionary theory. In the final four chapters, we turn our attention to social behaviour. Chapter When would it pay individuals to cooperate with either related or unrelated individuals?

We show how social theory can be tested in a variety of animals from microbes to meerkats. Chapter 12 is devoted to the social insects, where altruism reaches its most sophisticated development in the form of sterile worker castes.

We discuss new theory for the genetic predispositions and ecological factors promoting this remarkable behaviour, and show that there are often conflicts of interest even within the most cooperative societies. In Chapter 14, we discuss how natural selection shapes signals, focussing on the evolution of honesty and deception.

We also point to the flourishing interactions with other fields of research. The literature has become vast since the earlier editions of this book, so in this edition we have had to be even more selective. We hope that lecturers using this book will add their own favourite examples to those we have mentioned.

Throughout, we have tried to point to gaps in current theory and evidence. We hope that readers will be inspired not only to fill these, but also to discover new problems to solve. Do you like this book? Please share with your friends, let's read it!! Search Ebook here:.
