The Biological Bases of Human Behavior accomplishes what numerous introductory textbooks have failed to do: present an evolutionary explanation of “why it is we do what we do.” This comprehensive text brings together a diverse number of traditionally separate disciplines including paleoanthropology, psychology, and sociology in its attempt to understand human traits. Rich in controversial topics, this text integrates subjects such as paleontology, speech, the structure of the brain, “Eve,” and the rather “odd” way in which humans reproduce. Written as a narrative, this excellent learning tool relates modern behavior to the past environments, stresses, and challenges still evident in the modern human world.
