This study argues that much research of the emotions has been misguided. It attempts to show that "emotion" encompasses psychological states of very different, and thus not comparable, kinds. Some emotions, such as a brief flaring up of anger in response to some experience, are evolutionary ancient, reflex-like responses which appear insensitive to culture. Others, like moral guilt, differ importantly across cultures, despite their long history in humans, and affinity to behaviour seen in other species. Yet other emotions appear to be the acting-out of today's psychological myths, as ghost possession acted out the metaphysical myths of past centuries. These three kinds of responses have different evolutionary origins, different adaptive functions, different biological bases, and different roles in human psychology. The concept that binds them together, emotion, plays no useful role, since there is no object of scientific knowledge that corresponds to it. A detailed overview of the relevant theoretical approaches is provided in this text, assessing the relative merits of three main theoretical approaches: affect programme theory, evolutionary psychology, and social constructionism.

Is the history of life a series of accidents or a drama scripted by selfish genes? Is there an "essential" human nature, determined at birth or in a distant evolutionary past? What should we conserve--species, ecosystems, or something else?
Informed answers to questions like these, critical to our understanding of ourselves and the world around us, require both a knowledge of biology and a philosophical framework within which to make sense of its findings. In this accessible introduction to philosophy of biology, Kim Sterelny and Paul E. Griffiths present both the science and the philosophical context necessary for a critical understanding of the most exciting debates shaping biology today. The authors, both of whom have published extensively in this field, describe the range of competing views--including their own--on these fascinating topics.
With its clear explanations of both biological and philosophical concepts, "Sex and Death" will appeal not only to undergraduates, but also to the many general readers eager to think critically about the science of life.

The nature/nurture debate is not dead. Dichotomous views of development still underlie many fundamental debates in the biological and social sciences. Developmental systems theory (DST) offers a new conceptual framework with which to resolve such debates. DST views ontogeny as contingent cycles of interaction among a varied set of developmental resources, no one of which controls the process. These factors include DNA, cellular and organismic structure, and social and ecological interactions. DST has excited interest from a wide range of researchers, from molecular biologists to anthropologists, because of its ability to integrate evolutionary theory and other disciplines without falling into traditional oppositions.The book provides historical background to DST, recent theoretical findings on the mechanisms of heredity, applications of the DST framework to behavioral development, implications of DST for the philosophy of biology, and critical reactions to DST.
