Evolutionary Psychopathology takes steps toward a unified approach to psychopathology, using the concepts of life history theory - a biological account of how individual differences in development, physiology and behavior arise from tradeoffs in survival and reproduction - to build an integrative framework for mental disorders. This book reviews existing evolutionary models of specific conditions and connects them in a broader perspective, with the goal ofexplaining the large-scale patterns of risk and comorbidity that characterize psychopathology.
