The non-kin cooperation problem is not solved in proximal killers. The non-kin cooperation problem is solved in remote killers: b ccoop < ccoerc, b ccoop > ccoerc. African bee eaters: kinship-dependent social breeder: only family feed and raise their kin, they don"t participate in kinship-independent social breeding. Humans are the only animals in the world who participate in kin-ship independent social breeding: ex. We have hospitals/ doctors to deliver the baby safely. Random strangers are helping non-kin to give birth smoothly: it takes a village to raise a human child. Inexpensive coercion > adaptive management of conflicts of interest.
