While evolutionary psychology is a fascinating science, it is also often misunderstood. In this highly acclaimed undergraduate textbook, Workman and Reader assume no prior knowledge of evolution and instead carefully guide students towards a level of understanding where they can critically apply evolutionary theory to psychological explanation. The authors provide an engaging and balanced discussion of evolutionary psychology without committing to a specific school of thought, and organise chapters around topics familiar to psychology students. Retaining the successful structure and pedagogy of previous editions, the text has been updated to include the latest advances in the field, with new material added on homosexuality, a consideration of feminist criticism, grandparental investment, and developments in neuroscience and epigenetics. The fourth edition is now in full colour, with new figures and photographs, revised boxed case studies, additional discussion questions, and an updated online test bank.
