Table 2. Summary of the most important results and their relevance to the hypotheses.

Genetically variable trait	Evidence that the trait functions in social environment construction	Constructed environment	Evidence that the constructed environment influences behavioral development	Consistent with hypothesis
Aggression	More aggressive males are attacked more	Aggression in social group	Experience of being attacked leads to reduced aggression later	1
Group-size preference	Males are attacked more in their preferred group compared with their unpreferred group	Aggression in social group	Experience of being attacked leads to reduced aggression later	2

Summary of the most important results and their relevance to the hypotheses (detailed in the Introduction) about how genetic variation in social environment construction may affect behavioral development.
