Before revision:  follow a downward heuristic to structure their fights, spreading aggression relatively equally across lower-ranked opponents but 50 groups (29\%) use strategies that are indicative of more detailed rank information . Strategies are not phylogenetically constrained and  groups within the same species can use different strategies, indicating that the choice of heuristics may be contextual and that the structuring of aggression by social information should not be considered a fixed characteristic .
After revision:  follow a downward heuristic , but a significant minority (38 groups, 22\%) show more complex social dominance patterns (close competitors or bullying) consistent with higher levels of social information use. These patterns are not phylogenetically constrained and groups within the same species can use different strategies, indicating that the choice of heuristics may be contextual and that the structuring of aggression by social information should not be considered a fixed characteristic .
