The evolutionary view of psychopathy posits that “the risk taking, opportunistic, and callous behavior” characteristic of psychopaths would have increased reproductive success in ancestral environments. These traits would emerge when they are expected to promote fitness. For example, under conditions of a high ratio of cooperators to psychopaths, psychopathic individuals could exploit trusting and cooperative others to enhance their reproductive opportunities. Psychopathic traits in such conditions would have been favoured by selection. In neuroscience it is thought that psychopathy in part is related to a dysfunction in the amygdala<ref>Weber, S., Habel, U., Amunts, K., & Schneider, F. (2008).
