The evolutionary turn in psychiatry: a historical overview

Ever since Darwin, psychiatrists have been tempted to put evolutionary theory to use in their efforts to understand and explain various aspects of mental disorders. Following a number of pivotal developments in the history of evolutionary thought, including degeneration theory, ethology and the modern synthesis, this introductory paper provides an overview of the many trends and schools in the history of 'psychiatric Darwinism' and 'evolutionary psychiatry'. We conclude with an attempt to distinguish three underlying motives in asking evolutionary questions about mental disorders.
