Behavior genetics, addresses how traits are passed from parent to child and shared by biological relatives. Evolutionary psychology, addresses how patterns of behavior that characterized all humans may have originated in the survival value these characteristics provided over the history of the species. The field of research examines the way inherited biological material-genes- can influence across situations a personality trait.

The field of behavioral genetics has been controversial from the beginning in part because of its historic association with a couple of notorious ideas. One is eugenics, the belief that humanity could (and should) be improved through selective breeding. A second controversial idea to emerge from eugenics is cloning, the belief that it might be technologically possible to produce a complete duplicate-psychological as well as physical- of a human being.
