Long before the first word was ever spoken, laughter was already ancient. Researchers at the Universities of Warwick and Portsmouth have found that all five living great ape species share the same rhythmic structure in their laughter — a pattern so fundamental it traces back to a common ancestor some 15 million years ago. What separates humans is not the possession of this gift, but the subtle, socially attuned way we have learned to vary it. The study quietly reframes human communication not as a sudden leap, but as the latest refinement of something our lineage has carried for an almost inco
