age of these topics is perhaps the most thorough of any in the book.Chapter 13 discusses the evolutionary history of behavioral patterns.The chapter begins by outlining how one might investigate evolutionary history and uses communication in various species to illustrate major points.Later in the chapter it becomes evident that the author is attempting to cover the topic of communication simply with these illustrations and supplementary material at the end of the chapter.Although communication is not treated in detail, coverage does range from an ethologist's view of conflict in displays to J. Krebs' Beau Geste hypothesis of deceit.Chapter 14 deals with the evolution of societies and the costs and benefits of group living.Current sociobiological thinking is much in evidence in the author's discussion of such topics as helpers at the nest and eusociality in insects.The author relies strongly on kin selection to explain what appears to be cooperative or altruistic behavior.For example, the author chooses to emphasize the role of kin selection in the reproductive behavior of male lions and turkeys despite recent challenges (which the author does cite).Yet from his account, a reader still would not realize that the genetic relatedness of Rio Grande Turkey "brothers" was never known.We support Maynard Smith (1982, Current problems in sociobiology, King's College Sociobiology Group, p. 2) in thinking that the idea of kin selection has been overemphasized by sociobiologists at the expense of mutualism.
