Document Summary
Primary and secondary psychopathy (not going to be tested on: are humans born good or evil, psychopathy is a personality disorder characterized by a lack of emotions, callousness, charisma and irresponsibility. Studies suggest that both primary and secondary variants exist with secondary variants displaying more neuroses: certain genes determine psychopathy, but others have been exposed to traumatic events but don"t have the genes. Darwin"s theory of evolution: darwin suggests evolution, darwin presented 3 kinds of evidence, fossil records, structural similarities, selective breeding, darwin argued for natural selection.
