The development of the cerebral cortex introduced into the human brain the ability to ignore or override those instincts/reflexes that limit aggressive behavior in animals. The physiologically triggered "peacening" responses that occur in an aggressive animal when submission is signaled by his opponent are easily overridden by the press of the human intellect determined to achieve the conceptual reality for which aggression is initiated.
