Evolutionary psychology is not a distinct branch of psychology, but rather a theoretical lens that is currently informing all branches of psychology. Understanding our evolution-our history-has benefits for living a rich, well-integrated life, not only heightening our sense of beauty and wonderment about the world, but giving us a logical and proven framework for taking better care of ourselves. Covering a range of topics, this book provides an up-to-date review of the ideas, issues, and applications of contemporary evolutionary psychology.
