Accordingly, formed more clustered hierarchies had dispersed hierarchies. A proximate explanation for this finding may be related differences how maintain their social networks. To determine whether the clustering hierarchy was reflected patterns cohesiveness, I compared network sizes coalition grooming partners each third hierarchy. calculated proportion available that were within category relatedness (0.5 ≥ r ≤ 0.004 = 0). High-ranking coalitions with large close relatives small distant relatives; middle-ranking supported an intermediate and, very few relatives. groomed nearly all relatives, whilst middle- Thus, levels appeared reflect cohesion, terms formation.
