If human beings disappear, who will be the next intelligent life? You don’t think of this member

Man is the only intelligent life on earth, born millions of years ago. The reason why human beings can rely on their own wisdom to stand at the top of the food chain and become the overlord of the earth. It mainly depends on the human brain.

Human beings have a brain with advanced intelligence. Our ancestors came down from the tree and walked upright, which started the continuous evolution of the brain and increased the brain capacity. On average, an adult’s brain weighs about 1400 grams. If a person’s weight is 65 kg, the brain accounts for 21.5%, which is a terrible proportion. You should know that the proportion of brain and weight of most other animals is only less than 1% of that of human beings.

Although human beings are intelligent life and have formed human civilization, and now have developed into scientific and technological civilization, none of us can be sure that human civilization will continue forever. In the 4.6 billion years since the birth of the earth, there have been too many creatures and overlords of different times, such as the overlord insects of the giant insect age and the dinosaurs of the dinosaur age. Dinosaurs ruled the earth for 160 million years, but finally they died out because of the disaster caused by asteroid impact.

But the time that human beings appeared is only millions of years, and no one knows how long they can last. If human beings disappear one day, who will be the most likely species to become the next intelligent life? Maybe many people think of big fishy, because it is closely related to human ancestors, and the more intelligent it is, the more animals it is.

So is that really the case? Xiao Bian is going to introduce another animal to his friends today. Although it has no gorgeous appearance, it is far more intelligent than other animals. It is the most likely species to become the next intelligent life after the disappearance of human beings. This animal is the crow. It’s a bird.

I believe many people are not unfamiliar with crows, and many people do not like it, especially in rural areas, crows are known as ominous birds. People in rural areas like to listen to magpies. When they find magpies standing on the roof of their houses, they will feel that there are good things to come. But if it’s a crow standing on the roof, nine times out of ten it will be driven away by farmers.

Crow is the common name of several black birds in the genus Corvidae of Passeriformes. It’s also called laogua. His mouth is very happy. It is the largest bird in Passeriformes, about 50 cm in length. The whole body or most of its feathers are black. The color of its feathers is black all over, which is not popular. Moreover, its cry is not very pleasant. No wonder many people don’t like crows.

But crows, which we don’t like very much, are the smartest of birds, and they are smarter than most animals, and their intelligence may surpass that of orangutans. Crows’ IQ is no lower than that of human five-year-old children, or even, in some cases, completely surpasses that of human five-year-old children, scientists said. How smart the crow is still needs a series of experiments to understand. Let’s take a look at some IQ tests that researchers have done for crows.

I believe everyone has heard the story of crows drinking water. When we were young, we often saw this story in textbooks. Maybe at that time, we thought it was just an animal story and a fiction. But the fact is not at all. Crows can really throw stones into bottles, raise the water pressure, and then drink water successfully.

Some experimenters prepared two cups, one filled with sand and the other with water. A few stones were placed on the table. The crow did not hesitate to pick up the stones and put them into the water cup. After putting a few stones, he tried to drink water and continued to put them.

Later, the experimenter increased the difficulty, this time prepared three cups, the first cup how to put the stone will not rise water, the second small cup can not put the stone, the third cup can put the stone, but the water is the second cup. I’m afraid it’s not easy for human five-year-old children to solve this problem, but the crow said with a smile that it can’t help me at all.

The crow threw a stone into the first cup, found that the water did not rise, and decided not to put it. The second cup observed that it could not put the stone, so it directly threw the stone into the right cup. As a result, it immediately found that the water in the second cup Rose, continued to lose a few pieces, and finally drank the water from the middle cup. Experiments have proved that crows have really high IQ.

Some friends may say, if you put a stone in the third cup, how can the water rise in the middle? This is actually two connected cups. The experimenter has to test whether the crow can think. It turns out that the crow can think. This kind of intelligence quotient can’t be achieved by ordinary five-year-old children. It needs smarter five-year-old children to think and do it.

The second experiment is that crows eat insects. We all know that there are many delicious insects in some gaps in some trees. If it is a woodpecker, it is easy to eat the insects because of its long and sharp mouth, but the crow’s mouth is not good. But crows can also easily eat the insects in the cracks, and the efficiency is higher than woodpeckers, so how do crows do it?

The researchers found that crows pick up some crooked branches, use them to hook out bugs in the cracks, and then enjoy the delicious food. If you think it’s that simple, you’re wrong. In order to test the crow’s intelligence, researchers specially find a box and put some food in it. If they want to eat the food in the box, they have to hook it out with branches.

The researchers did not provide long branches, but also provided some short branches, which could not touch the food in the box and could not hook out the food at all. If it were you, what would you do? Maybe a lot of people still have to think about how to do it, but the crow responded immediately. The crow found that there were holes at the end of some branches, so he inserted other branches into the holes and spliced the long branches to get delicious food. Among them, the highest record was four branches. Can a human five-year-old achieve such an IQ? Maybe some adults will not think of such a method, such intelligence is really very high.

There are some crows want to eat nuts, but they can’t break the hard shell, but it’s also difficult for the clever crows, they will hold nuts and wait by the road. When the red light is on, they throw the nuts in front of the tires of the stopped car and fly away. When the lights change from red to green, cars drive by, crushing the nut shells, and the crows fly back to enjoy the delicious food.

The extraordinary intelligence of crows has attracted the research of many scientists. In the past, people thought that chimpanzees were very intelligent animals, which were closest to human intelligence quotient. But later, it was found that the intelligence quotient of crows was even higher than that of chimpanzees. Why are crows so smart? Through research, scientists found that crows have the highest brain volume to body ratio in the animal kingdom, reaching 2.3%. This ratio is more than 10 times that of many animals. As we said above, the ratio of brain volume to body volume of most animals is below 0.1%, which may be the main reason why crows are extremely smart.

In fact, the crow’s intelligence is far beyond these experiments. Scientists have done many related experiments one after another and found that it is really a very intelligent bird and a really intelligent creature in the animal world. If one day, human really disappeared from the earth, the next to rule the earth, may not turn to orangutans or dolphins, but crows. What do you think of that?
