Wild shampanzi consumes the equivalent of 2 cocktails per day in the form of loud fruit.

In the forests of Uganda and Cote d’Ivoire, Chimpanzee The crowd in figs and plum trees, swinging on the fruit is sweet and soft and only a little boozy. A new study showed that these daily snacks calmly add to the equivalent of nearly two alcoholic drinks to humans.

A team of scientists at the University of California Berkeley and other institutions chimpanzees have already tested a snack: figs in the umbrella of Uganda and a thorny fruits on the floor of the forest in Cote d’Ivoire. The collection of data was not easy – with a little electricity that exceeds the solar panels and continuous humidity that threatens tools, the researchers spent three seasons in the transfer of equipment and calibration of testing groups to measure alcohol in many different tropical fruits.

In the end, they found that on average, the alcohol content in the fruit came at about 0.3 % by weight. This is at the level of Kombucha, but when chimpanzees eat 10 pounds of fruit per day and weigh about 90 pounds, it adds up to about 14 grams of ethanol, and equals about human cocktails.

But do not depic of chimpanzees swing drunk with trees. The researchers said that in order to drink drunk, they had to complain about the fruit until their stomachs excel. Instead, they were subjected to a steady low dose, a quiet sensation of the natural fermentation process.

The first author of the author of The Paper and Uc Berkeley, a professor of integrated biology, Robert Dudley, offered the “Monder Monkey” hypothesis in 2000, on the pretext that our attractiveness to alcohol can come from eating habits. Dodley has made it logical to be caught on alcohol, because their meals have long been revolving around ripe fruits.

“Once you start eating, it acts as an appetizer, “The pleasure of linking alcohol increases nutrition rates.”

Other animals are chasing the same duct as well.

“Open a bottle of beer outside and it appears that the fruit fly appears almost immediately,” said Dodley.

Spider monkeys in Panamaand Slow in Malaysia Even Elephant It is documented naturally consuming fermented fruits or nectar.

What makes this study different is that it provides the first direct chemical measurements of ethanol in the fruits that eat the wild chimpanzees routinely, then connect these numbers with daily entry.

The open question is whether the chilbzim is already choosing the fruit for alcohol content or just chasing sugar and calories. Either way, Dudley says the story is calling us.

“We inherited alcohol taste,” Dodley said. “Although our diet has varied … this bias for consumption quickly when this molecule is present can be strong.”
