Trying to understand why human beings like alcohol so much, these scientists have just found a fundamental clue: drunken monkeys

More than two decades ago, Robert Dudley wondered how it was possible that we liked alcohol. In 2014, the evolutionary biologist of the University of California in Berkeley published “El Mono drunk”, a book where he explored The evolutionary roots of that transcultural hobby to alcohol.

According to Dudley, it is the fans of primates to fermented fruits (rich in sugars and with a very light alcoholic content) what is behind all this. The problem, as with all the hypotheses of evolutionary biology, was to demonstrate it.

Now we have found some tests. Because Science Advance magazine He has just published a study which shows that wild chimpanzees consume the alcoholic equivalent to one or two human cups. That is, exposure to this substance is regular and “probably” was also in our past as a kind, as Dudley said.

How have you discovered it? The team analyzed the fruits consumed by the wild chimpanzees in Uganda and in Ivory Coast. Thus, they discovered that these 21 species had a concentration of 0.3% alcohol on average. To the extent that these animals consume about 4.5 kilos of fruit, the amount of ethanol consumed daily is more than the 14 grams that has a standard glass in the US.

Of course, “by adjusting for body weight, which in chimpanzees is around 40 kilos in front of about 70 in humans, the exposure equals almost two glasses,” Explain in SINKSEY MARO, main author of the study.

It is true, however, that as consumed throughout the day, researchers have not found signs of drunkenness in chimpanzees.

So drink alcohol is something natural? This is a usual confusion when we put on the table lAs evolutionary explanationsbut evidently it is not prices. To start because there is nothing ‘natural’ per se. The Natural-artificial ‘distinction It is something that has very little scientific, philosophical or social basis. We have reached a point where everything is artificial.

But, on the other hand, the world has changed a lot. Although the hypothesis can explain the origin of the taste for alcohol in all human societies, constant exposure to alcohol of great concentration such as the one we suffer today has nothing to do with that of our ancestors.

Therefore, our taste for alcohol may have a certain evolutionary base; The abuse of ethanol and the health problems it causes are something else. Something much more dangerous.
