This book asks whether evolution can help us to understand human behaviour and explores diverse evolutionary methods and arguments. It provides a short, readable introduction to the science behind the works of Dawkins, Dennett, Wilson and Pinker. It is widely used in undergraduate courses around the world.

To properly understand behavior, we must obtain both ultimate and proximate explanations. Put briefly, ultimate explanations are concerned with why a behavior exists, and proximate explanations are concerned with how it works. These two types of explanation are complementary and the distinction is critical to evolutionary explanation. We are concerned that they have become conflated in some areas of the evolutionary literature on human behavior. This article brings attention to these issues. We focus on three specific areas: the evolution of (...) cooperation, transmitted culture, and epigenetics. We do this to avoid confusion and wasted effort—dangers that are particularly acute in interdisciplinary research. Throughout this article, we suggest ways in which misunderstanding may be avoided in the future. (shrink)

The present volume is, we believe, the first-ever edited volume devoted to the emotion of disgust. In this chapter we address the following issues: 1. Why was disgust almost completely ignored until about 1990, 2. Why has there been a great increase in attention to disgust since about 1990?, 3. The outline of an integrative, body-to-soul preadaptation theory of disgust, 4. Some specific features of disgust that make it particularly susceptible to laboratory research and particularly appropriate to address some fundamental (...) issues in psychology. In the final section, we outline some new questions that arise from the recent increased interest in disgust in the areas of brain mechanisms, psychopathology, the psychometric approach to the structure of disgust, and disgust and morality. We then indicate some important aspects of disgust that have yet to receive systematic investigation. (shrink)

THE MORAL ANIMAL examines the significance of this extraordinary shift in our perception of morality and what it means to be human. Taking the life of Charles Darwin as his context, Robert Wright brilliantly demonstrates how Darwin's ideas have stood the test of time, drawing startling conclusions about the structure of some of our most basic preoccupations. Why do we commit adultery, express suicidal tendencies and have the capacity for self-deception? Wright not only provides the answers to such fundamental moral (...) questions from the perspective of evolutionary psychology but challenges us to see ourselves anew through the clarifying lens of this fledgling and exciting science.
