This was the book that introduced me to Evolutionary Psychology several years ago. Since then, I have read The Anatomy of Love by Helen Fisher (which got the highest possible recommendation from the U of Chicago Feminist Majority Book Review - they called it "just plain wrong"), The Evolution of Desire by David Buss, Chimpanzee Politics, Peacemaking among Primates and Good Natured by Franz de Waal and The Adapted Mind, edited by Jerome Barkow, Leda Cosmides and James Tooby. Of these, I would rate The Adapted Mind as a better (but much more technical) introduction to Evolutionary Psychology, The Evolution of Desire as the most interesting, and Good Natured as the least depressing. Unlike Wright, the other authors have done a lot of original research and their books are cited in Wright's book. Furthermore, Wright's and Fisher's books seem the least straightforward and worst organized of the lot. One more point, if you're looking to uplift your spirits and improve your self-esteem, stay away from these books in general and Wright's book in particular. De Waal said that a fundamental thesis of Wright's book was that we are "all hypocrites in constant denial of our thoroughly selfish nature," and both Wright and de Waal are probably correct. Then again, this level of inwardly directed cynicism is something that we all could stand to develop.
