Westudy an evolutionary spatial prisoner's dilemma game where the fitnessof the players is determined by both the payoffs fromthe current interaction and their history. We consider the situationwhere the selection time scale is slower than the interactiontime scale. This is done by implementing probabilistic reproduction onan individual level. We observe that both too fast andtoo slow reproduction rates hamper the emergence of cooperation. Inother words, there exists an intermediate selection time scale thatmaximizes cooperation. Another factor we find to promote cooperation isa diversity of reproduction time scales.
