Chimpanzees Like Drinking 'Alcohol' Too
A 17-year study found chimpanzees will seek out and drink the alcohol in fermenting tree sap, but they don't appear to get drunk.By Evan Thomas | June 10, 2015
Researchers have found some chimpanzees in West Africa are habitual drinkers.
The 17-year study marks the first observations of repeated and habitual alcohol consumption by any wild ape.
Researchers observed chimpanzees using wadded-up leaves as sponges to drink raffia palm sap, which turns into an alcohol when it ferments. The sap is about 3 percent alcohol by volume, roughly equivalent to a really light beer. (Video via The Royal Society)
