comes into play. I say "type of, type of" because even inside the wild state of the animals there's a sort of unstated code all of them abide by. This code is that aggression and violence is most effective expressed while important. Which means, when the need for food requires it, or to guard oneself from a risk or protecting one's territory. But, the exception to this rule is the expression of aggression and violence between males to determine who has the right to mate and/or lead the institution. Here you'll see that majority of the alpha males are the more youthful mature, large, and more potent adult males .
