“At the core of all societies, I will show, is the social suite: (1) The capacity to have and recognize individual identity (2) Love for partners and offspring (3) Friendship (4) Social networks (5) Cooperation (6) Preference for one’s own group (that is, “in-group bias”) (7) Mild hierarchy (that is, relative egalitarianism) (8) Social learning and teaching”
