Scientific reports, 10(1), 1-12.<\/p>\n<p><strong>Abstract<\/strong><\/p>\n<p>The Male Warrior Hypothesis (MWH) establishes that men\u2019s psychology has been shaped by inter-group competition to acquire and protect reproductive resources. In this context, sex-specific selective pressures would have favored cooperation with the members of one\u2019s group in combination with hostility towards outsiders. We investigate the role of developmental testosterone, as measured indirectly through static markers of prenatal testosterone (2D:4D digit ratio) and pubertal testosterone (body musculature and facial masculinity), on both cooperation and aggressive behavior in the context of intergroup conflict among men. Supporting the MWH, our results show that the intergroup conflict scenario promotes cooperation within group members and aggression toward outgroup members. Regarding the hormonal underpinnings of this phenomenon, we find that body musculature is positively associated with aggression and cooperation, but only for cooperation when context (inter-group competition) is taken into account. Finally, we did not find evidence that the formidability of the group affected individual rates of aggression or cooperation, controlling for individual characteristics.<\/p>\n<p>Read the paper <strong><a href=\"https:\/\/www.nature.com\/articles\/s41598-019-57259-0\" target=\"_blank\" rel=\"noopener noreferrer\">here<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mu\u00f1oz-Reyes, J.
