Wild chimps in Uganda regularly eat fermented fruit, consuming alcohol equivalent to one to two human drinks daily, research shows.
Wild chimpanzees in Uganda’s Kibale National Park regularly consume alcohol from fermented fruits, with urine tests from 20 chimps showing ethanol metabolites in 17, equivalent to one to two standard human drinks daily.
Researchers, including Aleksey Maro of UC Berkeley, used improvised tools to collect samples, confirming that alcohol intake is a natural part of their diet.
The findings support the “drunken monkey” hypothesis, suggesting human alcohol preference may have evolutionary roots in ancestral primate diets.
Males and adult females tested positive more often than juveniles or females in estrus, possibly due to competition for fermented fruit.
The study highlights that alcohol consumption is widespread among wild primates and may play a role in primate behavior and evolution.
