Chimps drinking a lager a day in ripe fruit, study finds

... Wild chimpanzees have been found to consume the equivalent of a bottle of lager's alcohol a day from eating ripened fruit, scientists say.

They say this is evidence humans may have got our taste for alcohol from common primate ancestors who relied on fermented fruit - a source of sugar and alcohol - for food.

"Human attraction to alcohol probably arose from this dietary heritage of our common ancestor with chimpanzees," said study researcher Aleksey Maro of the University of California, Berkeley.

Chimps, like many other animals, have been spotted feeding on ripe fruit lying on the forest floor, but this is the first study to make clear how much alcohol they might be consuming.

The research team measured the amount of ethanol, or pure alcohol, in fruits such as figs and plums eaten in large quantities by wild chimps in Cte d'Ivoire and Uganda.

Based on the amount of fruit they normally eat, the chimps were ingesting around 14 grams of ethanol -- equivalent to nearly two UK units, or roughly one 330ml bottle of lager. ...
