2019’s book of the year for me. This book argues that our traditional understanding of evolution as a genetic process occurring at an individual level is too narrow—instead, Wilson places evolutionary processes into a multi-dimensional, multi-level framework that allows us to apply Darwin to everything from chicken farms to public policy. David Sloan Wilson is a friend of CBS, and this book even has a chapter explaining how evolution can help us be better ACT therapists too. Highest recommendation.
