"This second edition of John Archer and Barbara Lloydas Sex and Gender is extremely wide-ranging and tackles challenging theoretical issues, including the ultimate origins of sex differences in human behavior. In bringing social, developmental, and evolutionary theories to bear on many different types of female and male behaviors, Archer and Lloyd have produced an intellectually sophisticated text. Yet, the writing is engaging and accessible to undergraduates. Another plus is that the research covered in the book stems from a wide range of cultures. This is a truly outstanding book!"
