altruism-2
Explanation
This comic tackles the philosophical question of whether Batman or Superman is a better superhero, but immediately pivots to evolutionary biology. One character argues that if you go back far enough, Superman and all the people he saves likely share a common ancestor -- meaning Superman's heroism might just be "kin selection," the evolutionary strategy of helping relatives to propagate shared genes. By this logic, Superman is "just doing kin selection" rather than being truly altruistic.
Batman, by contrast, is a non-powered human who gains no genetic fitness benefit from saving strangers and even endangers himself. The counter-argument is that Batman's altruism might genuinely be selfless -- or alternatively, that maybe "evolution just hasn't come up with a punishment for being generous to non-kin yet," implying that true altruism is simply an evolutionary glitch that hasn't been selected against.
The joke works by applying the cold logic of evolutionary biology to a pop-culture debate in a way that makes both sides uncomfortable. It parodies how evolutionary psychology enthusiasts try to reduce all human behavior to fitness optimization, while also poking fun at the Superman vs. Batman debate by reframing it in the most joyless, academic terms possible. The final panel's suggestion that altruism is just an "unpunished" evolutionary mistake is a darkly funny commentary on how reductive biological thinking can drain the meaning from noble behavior.
