SNAP Mock 2 - Reading Comprehension: The Evolutionary Roots of Human Altruism and Social Contracts

The evolutionary origin of human altruism has long puzzled evolutionary biologists and social theorists. Within strict Darwinian paradigms, natural selection favors individual survival and the propagation of genetic lineage, making self-sacrificing altruism toward unrelated strangers appear evolutionarily counterproductive. However, anthropological and behavioral studies indicate that human survival was historically predicated on hyper-cooperative social structures. Mechanisms such as reciprocal altruism, indirect reciprocity, and culturally enforced social norms enabled early human groups to punish free-riders and foster deep intra-group solidarity.

This evolutionary heritage creates a permanent behavioral duality in modern societal life. Humans remain deeply wired for tribal in-group cooperation while simultaneously possessing the cognitive capacity for universal moral empathy. Understanding this evolutionary tension is vital for addressing contemporary challenges such as political polarization, global migration crises, and cross-cultural diplomacy, proving that human morality is neither a purely divine gift nor a fragile cultural veneer, but an adaptive survival architecture forged across millennia.
