This book presents a roadmap for an evolutionary psychology of the twenty-first century. It brings together theory from biology and cognitive science to show how the brain can be composed of specialized adaptations, and yet also be an organ of plasticity. Although mental adaptations have typically been seen as monolithic, hardwired components frozen in the evolutionary past, this book presents a new view of mental adaptations as diverse and variable, with distinct functions and evolutionary histories that shape how they develop, what information they use, and what they do with it. The book describes how advances in evolutionary developmental biology can be applied to the brain by focusing on the design of the developmental systems that build it. Crucially, developmental systems can be adaptively plastic, designed by the process of natural selection to build adaptive phenotypes using the rich information available in our social and physical environments. This approach bridges the longstanding divide between nativist approaches to development, based on innateness, and empiricist approaches, based on learning. It shows how a view of humans as a flexible, culturally dependent species is compatible with a complexly specialized brain, and how the nature of our flexibility can be better understood by confronting the evolved design of the organ on which that flexibility depends.
