Dr. Russell's book is an excellent review of evolutionary psychology ideas with respect to the subtitle of Power, Sex, and Love. It is impossible for an author to place more than an overview in such a short sampling of ideas. Dr. Russell did an excellent job of attempting to convey some very complex ideas in a mode and manner relevent to the reading level of a general audience. Those readers requiring a more in-depth portrayal of on-going research data have not experienced work in the field nor have an intimate appreciation of the complexities involved in comparative evolutionary criteria. Had Dr. Russell been more explicit about pristine biological imperatives, fewer readers would have had the ability to comprehend the subject mattter. I applaud his efforts at attempting to make a very complex idea accessible to those open-minded intelligent individuals who would not otherwise have had an opportunity to consider such ideas.
