He measured the ethanol concentration within the fruit pulp and estimated how much alcohol an average chimp would consume given known feeding rates. Of the 20 urine samples from 19 different chimps, ...

Chimps really are "drunken monkeys" - and actively seek out alcohol in their native habitat, suggests new research. Urine testing confirmed alcohol consumption among wild African chimpanzees with 17 ...

Urine testing confirmed alcohol consumption among wild African chimpanzees with 17 out of 20 containing alcohol byproducts, likely from fermented fruit in their diet. A breathalyser is impractical for ...
