This book is a bit uneven. Some of the chapters don't seem to fit too well (such as the Zak chapter). However, the book's argument--that evolutionary theory suggests different policy solutions to problems than standard social science theory--is nicely illustrated by other chapters. Chapters by Ellis and McGuire/Gruter and Blank all get one thinking that a knowledge of human nature might be very helpful in figuring out how we might address public problems.Thus, while it is regrettable that some chapters wander away from the book's theme, those chapters that address the central issues of the book (as outlined in the introductory essay) serve a valuable purpose.
