Full Description
The last decade has witnessed an exciting change in our understanding of the way in which the mind operates and the reasons behind a myriad of human behaviours. The traditional idea that nurture trumps nature in explanations of human behaviour has been supplanted by the evolutionary argument that human beings share evolved mental architectures that govern their behaviour.
This volume is an introduction to evolutionary approaches to psychology, bringing together seminal work in the field and exploring the ways in which evolutionary psychological research can illuminate our understanding of human behaviours and nature. Together, the chapters in this volume present a fresh perspective on evolutionary approaches to psychology, critically evaluating the extant literature while maintaining the need for evolutionary psychologies.
