Do chimps consume alcohol daily from ripe fruits?

Question

Accepted Answer

Chimpanzees Regularly Consume Alcohol from Fermenting Fruits

Chimpanzees consume the equivalent of at least one alcoholic drink per day by ingesting ripe, fermenting fruits. Researchers measured the ethanol content of fruits consumed by chimpanzees in Africa, finding that the natural fermentation of sugars in these fruits produces alcohol. This daily intake is estimated to be around 14 grams (half an ounce) of alcohol per day for the animals.
Daily Alcohol Intake of Chimpanzees

Studies have revealed that chimpanzees consume approximately 14 grams of alcohol daily through their diet of ripe, fermenting fruits. This quantity, when adjusted for body size, is comparable to a human drinking a pint of beer each day. This consistent ingestion of alcohol is not considered a small amount but is typically consumed in a diluted form and associated with food.
The "Drunken Monkey Theory"

The findings support the "drunken monkey theory," which posits that humans' inclination towards alcohol and their ability to metabolise it originated from primate ancestors who regularly consumed fermented fruits. This theory, initially met with skepticism, has gained support as further research indicates that primates do consume fermented fruits and show a preference for those with higher alcohol content. The lead author of the study, Aleksey Maro, noted that this research demonstrates that chimpanzees, humans' closest living relatives, routinely ingest physiologically relevant doses of alcohol.
Implications for Understanding Human Alcohol Consumption

This research contributes to understanding the evolutionary origins of human alcohol consumption. By studying the dietary habits and alcohol intake of chimpanzees, scientists aim to gain insights into the biological and behavioural consequences of chronic, low-level ethanol exposure in non-human primates. The study highlights that the prevalence of ethanol in tropical fruits is a confirmed phenomenon, opening avenues for further investigation into the long-term effects on primate health and behaviour.
