Heard recently that they have isolated what causes prejudice and dominant behavior in humans. The thing that causes confidence in a person to master a task, or initiate a new task or idea, is a gene that affects the amygdala, and it gets mutated in some, which turns dominating a task,for them, into dominating and controlling other people. So they see people as things to conquer, like mastering golf or doing a job. It's where sexism and racism come from, dictators to the sweet voiced control freak you eat breakfast with. They have found the mutation in all races tested so far, and in both genders. (Explains a lot...)
