Modern application of evolutionary theory to psychology: key concepts and clarifications

Abstract

Darwinian selection has become the centerpiece of biology, and in the past few decades many psychologists and anthropologists have recognized the value of using an evolutionary perspective to guide their work. With a focus on evolved psychological mechanisms and associated information processing features, evolutionary psychology has risen as a compelling and fruitful approach to the study of human psychology and behavior. In this article we review the instrument of evolution: natural selection, the products of evolution, and the impact of evolutionary thinking on modern psychological science. We conclude that as prejudicial barriers are overcome, as more evolutionary psychological work is conducted, and as hypothesized psychological mechanisms are substantiated in other disciplines, evolutionary psychology will emerge as the metatheory for psychology.
