Boozy chimps fail urine test, confirm hotly debated theory

Recent findings reveal that chimpanzees regularly consume fermented fruit, leading to significant levels of alcohol byproducts in their urine. 16 out of 20 urine samples tested showed high levels of ethyl glucuronide, supporting the idea that their attraction to alcohol may share evolutionary roots with humans. This aligns with the 'drunken monkey hypothesis,' which suggests that our affinity for alcohol dates back to the origins of great apes.

Additionally, chimps are estimated to consume the equivalent of nearly two alcoholic drinks per day. Future research aims to investigate how this alcohol consumption affects their behavior and physiology, particularly in relation to female fertility. This could have broader implications for understanding alcohol's role in social behaviors across species.
