How high is the IQ of dolphins? Researcher: Not only has a high IQ, but he also has human personality traits

"Smart Creatures" Living in the Ocean

Although they are marine creatures, the ancestors of dolphins are terrestrial animals, and they are the same as humans. , is also a member of mammals. Compared with primates, except for the appearance that looks very different from humans, dolphins are very similar to humans in terms of sociality and personality traits.

Researchers even found that dolphins can even name each other, which is very interesting, because according to human understanding, in nature, it seems that only humans can name each other, and then they will Used to address. But dolphins actually do this, and they exchange names with each other. Even if they haven't seen each other for a long time, they can still call each other's name when they meet again.

After seeing this, some friends may say that dolphins cannot speak, so how do they call each other by name? This is because they use different calls, in a way similar to "whistling", to identify whether the other party is a familiar dolphin and call the other party's name at the same time.

This is the first time that scientists have seen this complex method of communication in creatures other than humans. Therefore, researchers believe that this may be because dolphins once had the same ancestor as humans.

The relationship between dolphins and humans

Although mammals did not start their real rapid evolution more than 60 million years ago after the mass extinction of the dinosaurs , but the earliest mammals existed at the same time as dinosaurs. Through genetic tracing, researchers said that about 95 million years ago, the ancestors of primates and dolphins had not yet separated, and they still belonged to the same species.

This means that whether it is primates, dolphins, or even humans, many of their characteristics may come from the same earliest ancestor. After they parted ways, although their evolutionary paths were different, But they still retain many similarities. Even as marine creatures, dolphins can make and use tools, which makes them one of the smartest animals on earth.

At present, scientists have not fully understood the personality characteristics of dolphins, but what is known is surprising enough, and these discoveries can once again prove that humans It is indeed the "native species" of the earth. Although some opinions believe that humans are a combination of alien creatures and terrestrial creatures, there are many animals on the earth that are very similar to us. This means that humans Emergence is not the result of transformation, but a miracle of evolution.

So, in addition to dolphins, which other animals in the animal kingdom have "intelligence" that surprises humans? Researchers say that humans have actually always ignored the intelligence of animals.

How smart can animals be?

In the northern hemisphere, especially in Bhutan, there is a magical creature - the raven. They are a kind of black bird, also known as the "fat-headed bird". Dan's Valley Bird. How smart is this bird? Studies have shown that their cognitive abilities are the same as those of chimpanzees, and they also have extremely strong logical abilities and know how to plan their own action goals. In many aspects, they are even as good as humans.

There are also rats, which are regarded as one of the "four pests". They are also one of the most intelligent animals on the earth. Studies have found that the brain structure of rats is very similar to that of humans. A large number of Neurons make mice smarter than we think, which is one of the reasons why scientists use mice in many experiments.

Similar situations still occur in many animals that we are familiar with, such as pigs, ducks, chickens, cows, etc. Although they are a source of food for humans, they provide They feel silly, especially pigs, which always give people a very clumsy feeling. However, in fact, these animals have unexpected intelligence.

Take cows, for example. Research has found that cows can remember human faces and voices. Dairy farm workers can tell whether the other worker is a new worker.

Isn’t it very interesting? The familiar story of "crows drinking water" also happens to raccoons. Researchers from the United States found that in order to get the food at the bottom of the container, raccoons will pass through stones in a way similar to "crows drinking water" Let the water level rise and then eat food.

These all mean that animals on the earth are far smarter than we think. So, when humans leave the earth in the future, which kind of creature do you think is likely to become What about the rulers?
