Again depending on the common goal, eventually twosomes and threesomes will integrate into larger sets of six or eight, with corresponding revisions of territory, dominance-ranking, and further differentiation of roles. All of this seldom takes place without some conflict or disagreement: for example, fighting over the distribution of resources, the choices of means and different subgoals, the development of what are appropriate norms, rewards and punishments. Some of these conflicts will be territorial in nature: i.e., jealousy over roles, or locations, or favored relationships. But most will be involved with struggles for status, ranging from mild protests to serious verbal conflicts and even dangerous violence.
