The first decision point in an intraspecies conflict usually involves deciding between fleeing or posturing. A threatened baboon or rooster who elects to stand its ground does not respond to aggression from one of his own kind by leaping instantly to the enemy’s throat. Instead, both creatures instinctively go through a series of posturing actions that, while intimidating, are almost always harmless. These actions are designed to convince an opponent, through both sight and sound, that the posturer is a dangerous and frightening adversary.
