Evolutionary psychiatry and depression: testing two hypotheses

Abstract

In the last few decades, there has been a genuine `adaptive turn' in psychiatry, resulting in evolutionary accounts for an increasing number of psychopathologies. In this paper, I explore the advantages and problems with the two main evolutionary approaches to depression, namely the mismatch and persistence accounts. I will argue that while both evolutionary theories of depression might provide some helpful perspectives, the accounts also harbor significant flaws that might question their authority and usefulness as explanations.
