# Oo oo, ha ha: why humans and great apes giggle alike when tickled

> **Open Intelligence Dossier** · First detected: 2026-06-25 20:07 UTC · Category: Science

## Executive Summary
Recent research reveals striking parallels between human and great ape laughter, suggesting deep evolutionary roots in vocal expression.

## Intelligence Brief
Scientists have analyzed the laughter of great apes to determine how it relates to human vocal patterns. The study specifically focused on how both humans and great apes react when tickled, identifying similarities in the rhythmic and temporal characteristics of their giggles.


Coverage from BBC Wildlife Magazine and Nature emphasizes that human vocal plasticity exists on a hominid continuum. These reports highlight that the mechanics of laughter are not exclusive to humans but share a common biological history with other great apes.


Future reports may provide further details on the specific evolutionary mechanisms linking these vocalizations. Current coverage does not yet specify how these findings might influence broader theories on the development of primate communication.
