Study Finds Urination Contagious Among Chimpanzees

A study published in Current Biology reveals that chimpanzees exhibit a behavior called contagious urination, where one chimp's urination prompts others to follow suit.
The research involved observing 20 chimpanzees at the Kumamoto Sanctuary for over 600 hours, documenting 1,328 urination instances.
Social rank influenced the behavior, with lower-ranking chimpanzees more likely to urinate when others did, suggesting a form of hidden leadership.
The study indicates that this behavior may help reinforce social bonds and group cohesion among chimpanzees, and parallels exist with human urination habits.
