Group culture selection and gene-culture coevolution can explain inter-group aggression

Group culture selection and gene-culture coevolution can explain most of the human traits obscure for ...(27 more characters.)
Traits like ultra-altruism, large-scale cooperation, longing for belonging to a group, and intergroup aggression are hard to explain through individual gene selection alone.
In comparison, Darwinian group selection (direct gene selection at the group level) has too many contingencies and, thus, is much less probable as the main selection force for these traits.
