Before revision:  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 . Instead, individuals may be able to plastically respond to local conditions by increasing or decreasing the complexity of their strategies .
