Coalitional Psychology (us versus them; collective action; perceptions of race; multi-individual cooperation)
Cooperation between 3 or more individuals who are not kin is rare in the animal kingdom, yet common in our species. How could this have evolved? See:

"Seeing" others as members of a race may not be inevitable, as many psychologists had thought. Instead, the tendency to notice and remember someone’s race may be a changeable byproduct of brain mechanisms that evolved for another reason: to detect shifting coalitions and alliances. By creating a social context in which race was uncorrelated with coalitional alliances, we were able to drastically decrease the extent to which subjects noticed and remembered other people’s race.
