The idea of "eusocial" species is what got me thinking about "euvoluntary" exchange in the first place.
Is eusociality adaptive? It is clearly adaptive for the hive, or the nest. But can we reconcile eusocial species with evolution?
Or would it be some kind of "choice," a collective decision to avoid competition among individuals in favor of competition among the equivalent of clans or bands?
