Evolution in 4 dimensions, revised Edition, by Eva Jablonka and Marion J Lamb (2014). There have been some very significant breakthroughs in Evolutionary theory in the last few years, many of which challenge the concept of all evolutionary change happening through genetic mechanisms. This opens up the possibility of understanding a much wider range of behaviours as being evolutionary adaptive but not fixed in the genome. This book is a very recent summary of these new research directions in Evolutionary theory, which broaden the field in exciting ways. I think this book is very important, and also has specific implications for understanding human mental health.
