What I am offering is a critical overview of ideas about depression some new some old which fall under the discipline of evolutionary psychology (EP). Do most types of depression represent an adaptation
- an evolved mechanism which has enhanced our survival & reproductive value in our ancestral environment? Has depression been selected? Could it still be useful to us today? This book makes a contribution to the field while communicating the issues to a wider audience than EP currently receives & deserves. There are important implications for how we should prevent or treat an increasingly common condition & how we might view the condition in a more constructive way."
