Show Summary Details


Humans are consummate niche constructors, and the cultivation of friendships may be a generalization of the same suite of abilities that permits humans to craft tools, fashion clothes, make fire pits, and build homes across so many diverse societies. Only more research will determine whether the psychological systems involved in cultivating a friendship and in guiding behaviors toward friends are the same as those used in more general kinds of niche construction and habit formation. A comparative perspective that examines the social behavior and brain organization of mammalian and avian relatives will be essential in this endeavor. In the face of this remarkable cross-cultural regularity, social and ecological circumstances also influence the specific functions of friendship and the relative importance of friendships compared to other institutions in a society.
