mentions the most similar animals on the earth to humans. Many people would think of chimpanzee , or a larger range-primates. However, a team of scientists from the University of Hull in the United Kingdom recently passed a period of nearly 10 After years of research, I discovered an interesting fact- dolphin actually possesses personality traits similar to humans.
"Intelligent creatures" living in the ocean
Although marine creatures, the ancestors of dolphins are terrestrial animals. They are also a member of mammals, just like humans. Compared with primates, dolphins are very similar to humans in terms of sociality and personality characteristics, except that their appearance is too different from that of humans.
Even researchers have discovered that dolphins even give each other names, which is very interesting, because according to human understanding, in nature, it seems that only humans can name each other and then use them as names. But the dolphins will do this, and they will exchange names with each other, even if they haven't seen each other for a long time, they can still call out each other's name when they meet again.
Seeing this, some friends may say that dolphins can't speak, how do they call each other by name? This is because they use different calls, similar to "whistling", to distinguish whether the other party is a familiar dolphin, and call each other's name at the same time.
This kind of complicated communication method is the first time that scientists have seen it in organisms other than humans. Therefore, researchers believe that this may be because dolphins once shared the same ancestor with humans.
The relationship between dolphins and humans
Although mammals were more than 60 million years ago,After the dinosaur extinction, the real rapid evolution began. However, the earliest mammals existed at the same time as the dinosaurs. Through genetic tracing, researchers said that about 95 million years ago, the ancestors of primates and dolphins were still there. Without separation, they still belong to the same species.
This means that whether it is a primate, a dolphin, or even a human, many of the characteristics of the body may have come from the same ancestor, and after parting ways, although the evolutionary path is different, there are still many The similarity of dolphins, even as marine creatures, dolphins will make and use tools, which makes them one of the smartest animals on earth.
At present, scientists have not fully figured out the personality characteristics of dolphins. However, what is known is surprising enough, and these findings can once again prove that human beings are indeed on the earth. "Indigenous species", although some views believe that humans are a combination of alien and terrestrial organisms, there are many animals on the earth that are extremely similar to us. All these mean that the emergence of humans is not modified The result is a miracle of evolution.
So, besides dolphins, in the animal kingdom, which other animals have surprising "IQ"? Researchers say that humans have actually ignored the intelligence of animals.
How smart can animals be?
In the northern hemisphere, especially Bhutan , there is a magical creature-the raven, which is a black bird, also known as the "fat-headed bird", but also Bhutan Valley bird. How smart is this bird? Studies have shown that they have the same cognitive abilities as chimpanzees, and they also have strong logical abilities, know how to plan their own action goals, and even in many ways, they are as good as humans.
There are also rats that are regarded as "one of the four pests"They are also one of the smartest animals on the planet. Studies have found that the brain structure of mice is very similar to the human brain structure. A large number of neurons makes mice smarter than we think. This is why in many experiments One of the reasons why scientists use mice to conduct experiments.
Similar situations still occur in many familiar animals, such as pigs, ducks, chickens, cows, etc., although they are used as human food sources, they give people a feeling Stupid, especially pigs, always give people a very clumsy feeling, but in fact, these animals have unexpected intelligence.
For example, dairy cows. Research has found that dairy cows can remember human faces and voices. For dairy cows, workers in dairy farms can tell whether they are new workers or not.
is not very interesting? The familiar story of " crow drinks water" is also staged on raccoons. Researchers from the United States have found that raccoons use a method similar to "crows drink water" in order to get food at the bottom of the container. Come through the stone to raise the water level, and then eat the food.
These all mean that the animals on the earth are much smarter than we think. Then, do you think that when humans leave the earth in the future, which kind of creature might become the ruler?
