Fairness-based morality is uniquely human despite similar selective conditions in animals.

Evidence

Baumard et al. propose a functional explanation for the evolution of a sense of fairness in humans: Fairness preferences are advantageous in an environment where individuals are in strong competition to be chosen for social interactions. Such conditions also exist in nonhuman animals. Therefore, it remains unclear why fairness (equated with morality) appears to be properly present only in humans. — Nicolas Baumard, A mutualistic approach to morality, 309

Categorization

• BMF: The puzzle that animals face identical partner-choice competition yet lack fairness/morality resonates with The Reluctant Fundamentalist’s question of when humans alone got singled out by norms — the uniquely-human moral capacity under identical selective pressures echoes Changez’s outsider scrutiny of American moral claims.
