Why do monkeys have bad tempers?

Monkeys can exhibit bad tempers due to their complex social structures and hierarchies, which often lead to competition for resources, mates, and status. Their emotions are closely tied to social interactions, and conflicts can arise from threats to their dominance or group dynamics. Additionally, stressors such as habitat loss and environmental changes can exacerbate aggressive behaviors. Overall, their tempers reflect both their evolutionary adaptations and the challenges they face in their environments.
