Thesis: Conflict served as propagating factors for the development of civilization almost as much as hunger. Territoriality, especially as pertaining to sex between early men and women, drove men wild with the desire to excel, for defense, revenge and jealousy, and a whole host of other factors. These are emotions in their most primal state. Eat, frak, kill, win, celebrate [vulgar body things], repeat without kill unless it becomes necessary. [Frak is always win.]
Frak is new F word.
