Answer to Question 1
When there is competition for scarce resources (females), the result is confrontational behavior and potentially serious violence. This pattern is known as the young male syndrome. It may partly be the consequence of long-ago evolutionary pressures and partly a response to situational demands. Although the pattern of behavior may be coded in every man's makeup, it is likely to appear among men whose present situations predict reproductive failure, e.g., unmarried and unemployed males.
