Why Don’t Apes Have Social Norms?
•Riedl et al. (2012). PNAS: they don’t care how others treat third-parties

Cooperation & Morality: Interdependence
Shared Agency => ‘We’
Partner Coordination & Choice => Equality
Normative Self-Regulation => ‘We’ > ‘Me’ Morality

Conclusion
✦ Human children are adapted for cooperation in ways that other great apes are not.
✦ These adaptations are fundamental to uniquely human processes of cognition, communication, culture, and morality.
