Expand on this week's Discussion 1 by describing an instance of interpersonal aggression that you have observed, heard about, read about, or viewed on film or video. Make the case that supports or does not support influences on the behavior (including the evolutionary case for the behavior). Address whether you think that multiple explanations for a behavior can co-exist. Can more than one explanation apply to the example that you have chosen? If not, why not? If so, why?
