In this commentary, we critique the appropriate behavioural features for evolutionary genetic analysis, the role of the environment, and the viability of a general evolutionary genetic model for all common mental disorders. In light of these issues, we suggest that the authors may have prematurely discounted the role of some of the mechanisms they review, particularly balancing selection.
1. By “no longer performing its naturally selected function,” we mean that the action of the mechanism either exacerbates the problem(s) it was designed to solve or creates a new problem that is more severe or debilitating.
