研究显示, 乌干达野生黑猩猩经常食用发酵水果, 每天饮用相当于1至2人饮料的酒精。 Wild chimps in Uganda regularly eat fermented fruit, consuming alcohol equivalent to one to two human drinks daily, research shows.

乌干达Kibale国家公园野生黑猩猩经常从发酵水果中饮用酒精, 20只黑猩猩的尿检显示17个黑猩猩有乙醇代谢物, 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. 包括加州大学伯克利分校的Aleksey Maro在内的研究人员使用简易工具收集样本,证实酒精摄入是其饮食的自然部分。 Researchers, including Aleksey Maro of UC Berkeley, used improvised tools to collect samples, confirming that alcohol intake is a natural part of their diet. 研究结果支持了“坏猴子”的假设,认为人类偏爱酒精可能会在祖先的灵长类动物饮食中产生进化根源。 The findings support the “drunken monkey” hypothesis, suggesting human alcohol preference may have evolutionary roots in ancestral primate diets. 雄性和成年雌性比幼或雌性更频繁呈阳性,可能是由于对发酵果实的竞争. Males and adult females tested positive more often than juveniles or females in estrus, possibly due to competition for fermented fruit. 这项研究强调,酒精消费在野生灵长类动物中很普遍,可能在灵长类动物的行为和演变中发挥作用。 The study highlights that alcohol consumption is widespread among wild primates and may play a role in primate behavior and evolution.
