For Junior/senior and graduate level courses in evolution of human behavior, human biology, human variation, psychology of behavior or evolutionary psychology taught in departments of anthropology, biology or psychology. Compiled by the editor of American Anthropologist, this new edition of a well known reader published by Simon & Schuster Custom Publishing is a collection of recent studies on the biological basis of human behavior. The various readings offer a broad perspective and represent the work of scientists from many disciplines. The volume offers a critical evaluation of the question of whether the behavioral patterns we see are genetically fixed and/or racially variable. It evaluates whether experts are now better able to answer this question, or whether this renewed interest is just a resurgence of the old racism and biological determinism of the past.
