Scientists have discovered a special "mutated gene" in the human brain, which may be the key to human intelligence

According to Darwin's theory of evolution, humans evolved from forest apes, and it is well known that 65 million years ago, an asteroid impact caused the extinction of the dinosaurs. Before the rise of mammals, dinosaurs went extinct, and after tens of millions of years of evolution, forest apes emerged.

Forest apes live in trees, which can effectively avoid natural enemies and live a leisurely life. However, with the change of the earth's ecological environment, the forest area continues to decrease, and forest apes are faced with the predicament of survival. Come down and walk towards the plain life.

These forest ancient apes are the common ancestor of humans and chimpanzees. After millions of years of evolution, these forest ancient apes living in the plains have also moved towards differentiation and embarked on different evolutionary paths, and some people have begun to embark on the path of intelligent evolution , became the ancestors of humans, and another part of the people continued to evolve along the original direction, and finally evolved into chimpanzees.

So how did the common ancestor of humans and chimpanzees diverge millions of years ago? What factors can cause the same population to diverge and take different evolutionary paths? To this end, scientists have been conducting research and exploration. According to Darwin's theory of evolution, genetic mutation is the core of biological evolution.

The common ancestors of humans and chimpanzees may have embarked on different evolutionary paths due to different directions of gene variation. The fundamental reason is that some ancient apes living in the plains have an unknown gene mutation in a certain direction, while humans The brain developed rapidly due to this particular genetic variation, became more complex, and eventually evolved into intelligent life.

So what genetic mutation changed the evolutionary path of forest ancient apes? Modern scientific research has found that the genetic similarity between humans and chimpanzees is as high as 99%, and only 1% of the genes are different. It's that 1% genetic difference that completely splits humans and chimpanzees into two distinct races,

The key to the evolution of human beings into intelligent life lies in the 1% genetic difference. What secrets does this part of genes hold? A recent study published in the American "Science" magazine showed that scientists have found a special "variant gene" in the human brain, which is one of the reasons why humans are smarter than chimpanzees and unique to humans.

Scientists have found that during the evolution of forest ancient apes, the ancestors of humans underwent genome variation at a certain period, and the genetic variation during this period gave rise to a special gene ARHGAP11B, which promotes brain development and makes it more complex. .

It is the formation of this unique gene that has continuously improved the IQ of human beings, completely surpassing chimpanzees, turning us into intelligent creatures, and the ancestors of chimpanzees did not have this special genetic mutation, so naturally there would be no intelligent life, just The IQ is a little higher than that of other animals.

The discovery of the unique ARHGAP11B gene in the human brain is of great significance for humans to explore the mysteries of intelligent life. It is precisely because of the lack of this "ARHGAP11B" gene that chimpanzees fail to evolve into intelligent life, and it is precisely because of this "ARHGAP11B" gene that humans embark on the road of intelligent evolution.

From this, it can be speculated that "ARHGAP11B" is the key to human beings becoming smart. So, can the amount of this gene determine a person's intelligence? Scientists have not been able to give an answer to this question. After all, we still don't know what role "ARHGAP11B" played in the evolution of human intelligence.

Therefore, whether the amount of ARHGAP11B gene determines the level of intelligence remains to be further studied by scientists. No matter how high the content of ARHGAP11B is, there is no doubt that it is related to intelligence and can also affect the intelligence of living things. By implanting the "ARHGAP11B" gene, the scientists did find that other animals were a little bit smarter than they were originally.

"ARHGAP11B" is likely to be a key point on the evolutionary path of intelligent and non-intelligent organisms. If we can truly understand the mystery of "ARHGAP11B", we may be able to rapidly evolve an organism into an intelligent organism through genetic technology: "Orangutan" The chimpanzee in The Rise is precisely because humans have injected a kind of intelligence gene that makes it an intelligent life.

Naturally, such genetic technology is not necessarily a good thing for human beings, and once human beings have mastered the method of making organisms evolve into intelligent life, other intelligent life may appear on the earth, which is not good for human beings information. The mountains we speak of cannot be two tigers, and it is difficult for one earth to tolerate the existence of two civilizations.

Because the resources of the earth are limited after all, if the second and third intelligent races appear, then the limited resources of the earth will be divided up, thus hindering the development of mankind. That's what we don't want to see. Some people may say that we have mastered the mystery of intelligent life, as long as we don't take the initiative to create it?

Having said so much, but it is very difficult to do this, because human beings have mastered the secret of nuclear energy, thus creating terrible nuclear weapons, and with the continuous development of human beings, the number of nuclear weapons is also increasing, right Earth and humanity pose a dire threat. If we got hold of nuclear energy, we would have no control over its application, leading to the development of all kinds of weapons of destruction.

In the same way, when human beings have mastered the mystery of the evolution of organisms into intelligent life, they cannot control various organisms to conduct experiments. Once an experimental accident occurs, it will lead to the horror scene in "Rise of the Planet of the Apes". Therefore, the "ARHGAP11B" gene is equivalent to a Pandora's box, once it is fully opened, a group of unknown demons may be released, thus threatening the survival of mankind.
