Kin selection explains cooperation only among genetically related relatives

Evidence

Many cooperative acts, however, like giving a ride, holding doors, or giving money to the needy, cannot be adequately described in terms of reciprocity so understood. One might, of course, describe such acts as examples of “generalized reciprocity,” a notion that, according to Sahlins who made it popular, “refers to transactions that are putatively altruistic, transactions on the line of assistance given and, if possible and necessary, assistance returned. […] This is not to say that handing over things in such form … generates no counter-obligation. But the counter is not stipulated by time, quantity, or quality: the expectation of reciprocity is indefinite” (Sahlins 1965, p. 147). Such forms of cooperation are indeed genuine and important. Their description in terms of “reciprocity” however, can be misleading if it leads one to expect that the evolution of generalized reciprocity could be explained by generalizing standard models of the evolution of strict reciprocity. Free-riding, which is already difficult to control in strict reciprocity situations, is plainly not controlled in these cases; hence, the evolution of generalized reciprocity cannot be explained in terms of partner control. … We prefer therefore to talk of “mutualism” rather than of “generalized reciprocity.” — Nicolas Baumard, A mutualistic approach to morality, 75 (#corroborates, via linked claim)
