Chimpanzees pee together and apparently associated with the unity of the group

We people We know that the yawning sticks.

All you have to do is mention it, so many are already starting to pull air into the lungs. Like maybe right now.

It seems that our close relative’s chimpanzee is having a similar discomfort. They have a staple for yawning – contagious peeing.

When one starts to go, many monkeys do the same in the same group soon.

The Japanese researcher ended in observation Ena Onishi From the University of Kyoto. For a long time, he and his team followed 20 chimpanzees in the Kumoto protected area, which moved in four groups.

He observed the chimpanze’s peeing with his groups more than 1,300 times. That is why he has the reasons to claim that the chimpanzees really urinated at the same time.

All the mimicry was realized within a minute, says Website Science Alert.

Kyoton The university’s doctoral student, Onishi, followed the mackerels of more than 600 hours.

“Together, urination can be seen as a social phenomenon,” says Onishi.

He calls the phenomenon with a word “catchy urination” when describing his research in biology Science Magazine on Current Biology.

Already in 2019, Onishi found that urination of monkeys is a contagious variety. He immediately wondered if it was perhaps a similar pattern of catchy behavior as yawning people.

The closer the chimpanzee was the original urine, the more certain it was.

Socially chimpanzees at the lowest levels of a group or herd were most likely to pee.

Why Chimpanzees do this? It is still a bit of a mystery.

“Infectious urination can help strengthen the group,” he says.

The study was limited to chimpanzees, which were free in the protected area, but in captivity. Many of the monkeys in the area had been rescued from biomedical research institutes.

If you follow monkeys in nature, you often see that chimpanzees really think about what they do as a group. That’s what the researcher says Martin Surbeck. He is an evolutionary biologist at Harvard University.

Surbeck said newspaper The New York Timesillethat he was not surprised by the discovery of Onish. At the same time, monkeys will probably behave in natural conditions.

Surbeck is studying the ecology of chimpanzees and dwarf mimicians, or bonobos behavior. He did not participate in the Japanese study.

“We can see this kind of imitation in other species that are social,” Surbeck says.

Together, peeing is sometimes seen in human communities. Popular Science Magazine According to the Italian word bill, it says:

“The one who does not pee in the company is either a thief or a spy.”

Japanese It was surprised that they found a new phenomenon through normal observation.

“Countless new things can be found in the daily chores of animals,” Onishi said, according to the New York Times.
