ReviewEvolutionary psychiatry. Adaptationist and nonadaptationist conceptualizations.
Darwin's theory of evolution, and in particular one of its mechanisms, natural selection, is being used as the explanatory cornerstone of many unsolved problems in human biology and human affairs. Psychiatry is an example of that. Darwinian psychiatry's main proponents endorse the adaptationist program to carry out their project to implement an evolutionary psychiatry. ⋯ The other mistake is biological; it is their belief that adaptation is the driving force of evolution while in fact it is just an outcome of evolution. The current status of the controversy between cognitive versus emotional experiences as essentially independent is reviewed, and evidence is presented, that they cannot be considered platonic, categorically independent functions of CNSs. These data, taken together, plus arguments derived from the high degree of plasticity of nervous systems, lead us to suggest a different approach to classification of mental diseases.
