“Bytes de science” is like a collection of stories. Beautiful stories that tell Jeevika in all its freshness. But also in all its complexity. A bracket to perform miracles in the treasures of the world. For this new episode, let’s take a look at an animal with which humans have many conversations: crab-eating macaques.
Everyone knows crab-eating macaws. also called,. It is the most common monkey in Southeast Asia. However, we have an apprehensive time for its existence. He was in danger of deforestation. But also because he was made a victim for medicine. Or put on plates. And even, can be used as a laboratory animal. So much so that by the late 2000s, he had become The best-selling of endangered wildlife species.
Today, crab-eating macaw is doing better. If we can say. Because he is held captive. The biggest such event has some naughty naughty creatures numbering 30,000.. Especially in the field of neuroscience.
At the same time, the crab-eating macaques have learned to capture the changed environment by humans. In form of, In Indonesia, where he searches for food near the temple of Uluwatu, which is 70 meters in height. And it is in these macaques today, in particular, that we are going to be interested. Because do you imagine they are showing Rather surprising for wild monkeys.
Macas know the value of things
The crab-eating macaque living on the side of the Uluwatu temple learned … racketeering. Glasses, camera,or even . He got used to stealing things from tourists. Preferably valuables. And then they patiently wait for something to eat in return – some food, 95% of the time – to return them to their owners. The more valuable they know that the stolen item is, the more they expect a reward that they appreciate.
Macaques can also be found in aWith humans. Celebrated by one of them Even lasted 17 minutes. 17 minutes during which the monkey refused to return the stolen item. Assuming that the reward given in return was not up to its value.
According to, This unique behavior is achieved through experience and observation. It is then passed from generation to generation. For at least 30 years. It is therefore a good example of how primates are able to adapt to the changes occurring in their environments. A proof of the cultural intelligence of the crab-eating macaques for a symbolic economy was culturally maintained.
Knowing this, researchers will now want to explore the intelligence of these monkeys a little more. See, for example, how they might react when uncertainty is introduced into the racketeering system they imposed. Will they prioritize immediate rewards even at low prices? Will they opt for a low-probability, high-yield award instead? Or conversely, rewards with high probability and low return? Like male players, will they make choices that are not always optimal? Or will the long-tailed macaques still continue to show … not so dumb?
