Is the history of human preference for alcohol linked to monkeys?

In research on spider monkeys, scientists have found that they find and eat fruits that are ripe and contain alcohol, which reinforces the notion that humans' drinking habits are inherited from biological ancestors. Found. '

A new study has found that spider monkeys usually look for ripe fruit that contains alcohol. Their practice reinforces the idea that humans 'inherited the love of alcohol from their biological ancestors.'

Professor Robert Dudley, a biologist at the University of California, Berkeley, proposed the hypothesis of 'alcoholic monkeys' in 2014, according to which the attraction to alcohol in our history is millions of years old when monkeys discovered that the smell of alcohol Towards fruit and nutritious fruits. 

But Professor Dudley's hypothesis was based on the knowledge that some of the fruits that monkeys ate contained 7% alcohol. They were unable to provide any evidence as to whether the apes and apes really did find the fruit that had the yeast in it or whether they could digest the alcohol.

Now, thanks to new research, scientists have collected fruits that were eaten or thrown away by black-handed spider monkeys. In this way, the scientists found out that the monkeys really preferred fruits that contained alcohol.

Researchers have learned that spider monkeys sniffed and bit the fruit called jubo, which humans have been using for thousands of years to make wine called chika. It usually contained between one and two percent alcohol.

Scientists also took urine samples from six spider monkeys and found alcohol in five of them. This shows that instead of just letting the alcohol out of their bodies, they were actually using it for energy.

According to Dr. Christina Campbell, lead author of the study and an archaeologist at California State University North Ridge: Which contains alcohol.

He added: "It's just a matter of research and more research is needed, but there seems to be some truth in the notion that the 'drunken monkeys' assumption is correct. The tendency to drink alcohol in humans is based on a deep connection with the fruit-eating monkeys that used to produce naturally occurring wine in ripe fruits. 

Professor Dudley, co-author of the study, which was published this month in the Royal Society's Open Science Journal, called it a direct test of the "drunken monkeys" hypothesis.

He says: 'The first thing is that the food they (monkeys) are eating contains alcohol and they eat a lot of fruit. The other thing is that they are actually making alcohol a part of their body. We don't know how much fruit they eat and what effect it has on their behavior and body, but it is certain that they do. 

Professor Dudley said that in the case of spider monkeys, "they may not be intoxicated because their stomachs are full before they reach the level of intoxication, but alcohol gives them some physical benefits." ۔ '

Professor Dudley added that 'the food they consume may have germicidal properties or the activity of yeast and germs may cause the fruit to digest faster. You can't rule out that possibility. "

Dr. Campbell said that monkeys may choose alcoholic beverages because fermented fruit gives them more calories than unleavened fruit and thus more energy.

Dr. Campbell said that human ancestors may have been similarly affected when deciding which fruit to eat.

He added: "It is possible that human ancestors preferred the choice of fruit that contained alcohol. Because such fruits have more calories. In the same way, the effects of alcohol on the brain and the server can result in its consumption and benefits in the form of calories.

Of course, the availability of alcohol today without filling the stomach with fermented fruit pulp means that it is easy to become over-consumed.

Researchers have argued that the high consumption of alcohol in modern times may be the result of a link between alcohol and its nutritional value in the ancestral era, but may also be helpful to society in dealing with the harms of alcohol use. 

"Drinking too much alcohol, like diabetes and obesity, can be seen as a disease of malnutrition," the study said.
