We have learned that nonhuman primates are very complex animals. Some nonhuman primates are political animals who use their social skills and abilities to move up the social ladder. Many reconcile with each other after disputes, cooperate to complete complex tasks, and share resources among each other. Research into primate behavior has helped us to understand ourselves. By studying nonhuman primates we can find the roots of our behavior and we can pinpoint the biological origins of human emotions and intelligence.
Nonhuman primates have emotions.
Joy, anger, sadness, and fear are all part of the emotional repotoire some nonhuman primates have. By studying our closest relatives we have discovered insights into the human condition. We are no longer the only animals to feel emotions, to have culture, and to have complex social lives. Therefore, we are less unique as a species than we use to assume.
