This book is designed to introduce the evolutionary origins of the human brain’s present structures and functions. Evolutionary neuropsychology is a new multidisciplinary science that embraces and uses empirical findings from the fields of evolution, neuroscience, cognitive sciences, psychology, anthropology, and archaeology. This book is designed for the intellectually curious, but styled especially for academics at any level and psychologists focusing on various aspects of human behavior. The bedrock foundation of evolutionary neuropsychology is the assumption that functionally specialized brain regions are adaptations naturally selected in response to various environmental challenges over the course of billions of years of evolution. These adaptations and their brain regions and circuitry may now serve new functions, which are called exaptations, and they are particularly involved in higher cognitive functions.
