Kyoto University Discovers Chimps' Social Urination Phenomenon

Jan 22, 2025 | News On Japan

KYOTO - Kyoto University has made a groundbreaking discovery, identifying the occurrence of the so-called "urination mimicry" phenomenon in chimpanzees for the first time globally.

One chimpanzee begins urinating, followed shortly by another nearby individual mimicking the act.

A study involving 20 chimpanzees revealed that individuals near a urinating chimpanzee are more likely to urinate shortly afterward.

Professor Shinya Yamamoto from Kyoto University's Institute for the Future of Human Society commented:

"Urination is observed in various animals, enabling comparative studies. This finding offers an intriguing perspective on the evolution of sociality in animals and humans."
