Mama's Last Hug: Animal Emotions and What They Tell Us about Ourselves Quotes

“The human smile derives from the nervous grin found in other primates. We employ it when there is a potential for conflict, something we are always worried about even under the friendliest circumstances. We bring flowers or a bottle of wine when we are invading other people’s home territory, and we greet each other by waving an open hand, a gesture thought to originate from showing that we carry no weapons. But the smile remains our main tool to improve the mood. Copying another’s smile makes everyone happier, or as Louis Armstrong sang: “When you’re smiling, the whole world smiles with you.”

“Reprimanded children sometimes can’t stop smiling, which risks being mistaken for disrespect. All they’re doing, though, is nervously signaling nonhostility. This is why women smile more than men, and why men who smile are often in need of friendly relations. One study explicitly looked at this underdog quality of the smile in pictures taken right before matches in the Ultimate Fighting Championship. The photographs show both fighters defiantly staring at each other. Analysis of a large number of pictures revealed that the fighter with the more intense smile was the one who’d end up losing the fight later that day. The investigators concluded that smiling indicates a lack of physical dominance, and that the fighter who smiles the most is the one most in need of appeasement.”
