Xinhua News Agency, Beijing, May 29, New Media Special Report French media said that experiments show that green long-tailed monkeys and long-tailed black-jawed monkeys living on both sides of the African continentKomiks 1960 witch cloth draw although at 35They embarked on different paths of evolution 00,000 years ago, but when they were in danger, they used the same vocabulary.

AFP reported on May 27 that the new study published in the British journal Nature Ecology and Evolution that day not only illustrates how primates—including humans—cope with threats, but also illustrates the basic composition of language itself.

The long-tailed black-jawed monkey living on the East African savannah makes three different calls when it discovers three major natural enemies, leopards, snakes and eagles.

Monkeys who hear the cry but cannot see their natural enemies will respond accordingly: the cry about leopards will prompt them to climb a tree, the cry about snakes will prompt them to stand still, and the cry about eagles will cause them to scan the sky and find a place to hide.

It’s like a sentry shouting, “Don’t move, there’s a snake!” or “Leave the ground, there’s a leopard!”

The main author of the research report, Yulia Fischer, head of the cognitive ethics laboratory at the German Primate Center, pointed out that these unique warning calls were discovered 30 years ago, triggering debate about whether it was the original vocabulary.

This also raises questions about its origin. Babaylan 1990 cloth drawDid the cubs of the long-tailed black-jawed monkey learn these calls by imitating adult monkeys? Or are these calls delivered through genes?

To deepen our understanding, Fischer and his colleagues had an idea: “We decided to introduce a Komiks 1960 witch cloth draw drone to fly over the green long-tailed monkey community, and let them Cinema 1950 witch cloth draw exposed to potential dangers from the sky that had never been encountered before.”

The drone flew over these defenselessly in the air about 60 metersKomiks 1960 witch cloth drawPrepared monkeys. The monkeys responded immediately after discovering the drone: they sired and then hurriedly sought cover.

This call is not only different from the Babaylan 1990 cloth draw reaction to leopards or snakes, but is also “surprisingly similar” to the call made by the long-tailed black-jawed monkey in East Africa.

Fischer noted: “Despite the evolutionary differences of 3.5 million years, the call structure has basically not changed.”

In terms of evolutionary biologists, Komiks 1960 witch cloth draw, the warning of danger is “highly preserved.”

SameBabaylan 1990 cloth drawKurt Hammerschmidt from the German Primate Research Center said the fact that green long-tail monkeys respond to drones rather than other large birds in the region suggests a tiny but important difference. “The warning scream has nothing to do with the eagle itself. It seems to correspond to Cinema 1950 witch cloth draw a wider category: ‘Flying stuff’.”

To find out what monkeys learned from the incident where drones flew over, scientists conducted a second experiment a few days later. They Cinema 1950 witch cloth draw hid a loudspeaker next to a monkey looking for food alone and played back the sound of the drone. “After hearing the sound, the monkey looked up and searched the sky.” The second test showed that just one exposure to the new threat was enough to let the monkeys know the meaning of the warning call, which showed that they had extraordinary adaptability.

The researchers speculate that the monkey calls from hereditary—and its accompanying meaning—are similar to those made by human babies.

Hamerchmidt said: “When a child is born, he has the innate language ability before he learns to speak, such as moaning, laughing and crying.”

For some reason, humans have learned to transcend these inherent words and have made new voices with new meanings. But at all levels of culture and learning, some core reactions that fall within the category of evolutionary psychology remain.
