Drawing evidence from an array of disciplines including paleontology, anthropology, comparative psychology, and cognitive neuroscience, Evolutionary Psychology: The Ultimate Origins of Human Behavior explains how certain patterns of human behavior developed over time in order to insure survival and reproduction. Human behavioral tendencies are the result of both environmental selective pressures and sexual selection. Moreover, in order to explain human behavior in a holistic way the text weaves evolutionary explanations into a framework that incorporates ontogeny and physiological mechanisms, as well as immediate causation. It reviews how evolutionary psychology explains and predicts human behavior in a variety of contexts such as mate selection and striving for higher social status. Primary topics addressed are human origins, evolution of the brain and mind, language, mating, development, social behavior, tool use, art, and the challenges of adjusting our evolved psychological tendencies to the modern environment.
