Chimpanzees can recognize each other by the buttocks.
Infact verdict: Mostly True (79/100).
The claim that chimpanzees can recognize each other by the buttocks is supported by several medium-reliability sources. These studies show that chimpanzees exhibit a 'buttocks inversion effect', similar to the 'face inversion effect' in humans, indicating that they use visual recognition of buttocks for social purposes. While these sources are not from top-tier academic journals, they provide a consistent consensus supporting the claim. No opposing evidence was found.
