interdemic

Take the classic account of the efficacy of interdemic or group selection, the case that even G.C. Williams acknowledged was hierarchical selection.

Wright's interdemic group selection model involves groups only as interactors, not as manifestors of group-level adaptations.

Wright distinguishes between what he calls “intergroup selection,” that is, interdemic selection in his shifting balance process, and “group selection for group advantage”

Interestingly, Ford and his colleagues believed that genetic subdivision of the sort postulated by Wright would promote rapid evolution but for very different genetic reasons and by different genetic mechanisms (natural selection instead of random genetic drift, local selection, and interdemic selection).
