which falls as the residual pool of defectors, 1 - x - y , shrinks. Once a group happens to reach a state where . punishing costs less at the margin than plain, unpunishing cooperation does, and ordinary within-group selection stops working against the punishing type in that group. If groups that reach this state also out-compete or out-reproduce groups that never do — amplified, the authors argue, by cultural transmission mechanisms such as conformist imitation of locally common strategies, which are not available to purely genetic evolution — group-level selection can carry punishment, and the large-scale cooperation it sustains, to frequencies individual selection alone…
