Chimpanzees consume the equivalent of more than two alcoholic drinks per day
- Researchers led by Aleksey Maro measured chimpanzees' daily alcohol intake at two African sites, finding they consume about 14 grams of ethanol per day.
- This study tests the longstanding 'drunken monkey' hypothesis, which suggests that humans inherited an attraction to alcohol from primate ancestors who ate fermented fruit.
- Chimpanzees at Ngogo in Uganda and Taï in Ivory Coast favor fruits with around 0.3 percent alcohol content, such as figs and Parinari excelsa plums, which ferment naturally on trees.
- Maro explained that, adjusted for body mass, the chimpanzees' ethanol consumption equals about two glasses of wine per day, and the relationship with alcohol dates back 30 million years.
- The findings imply that alcohol exposure played a role in primate diets and evolution and highlight the need for further research into alcohol's biological and behavioral effects.
