If that's Homo sapiens......

And what did the mysterious man do to Homo sapiens?

If that guy is right, the mysterious man may have interfered with the evolutionary history of humans in the 25th century, and he made the ancient apes that could not walk upright walk upright in an instant, but what about Homo sapiens?

Homo sapiens is already close to modern man, late Homo sapiens even degraded body hair, with language and labor, with sociality and class, at this point, what else does the mysterious man need to do to Homo sapiens?

Forced evolution again?

Chen Shi's eyes stared at the Homo sapiens who was kneeling on the ground, and in a confused state, it didn't seem to know what was going on, and it still knelt on the ground and didn't stand up.

Somehow, Chen Shi suddenly remembered that when he was in college, he had listened to a lecture by an anthropologist professor.

If you want to ask ordinary people, what is the biggest difference between humans and other animals?

Well, many people will say, it's intelligence!

Yes, intelligence determines the fundamental difference between human beings and other animals, intelligence has made human beings the master of the earth's food chain, and intelligence has created the glorious historical civilization of human beings.

And the source of intelligence lies in the human brain.

The brain capacity of the human brain has evolved from a small age to become larger, and the increase in the brain capacity is also determining the changes in human intelligence, so that more things can be thought, tools can be made, etc., which also distinguishes the biggest difference between humans and other animals.

In this way, under the natural rules of natural selection, nature should make the brain bigger and bigger, and the brain capacity is higher and higher, but if this is really the case, why didn't other species with the same starting point for the original brain capacity upgrade their brains tens of millions of years ago? Didn't continue to improve your intelligence?

Why is it that only the genus Homo has evolved such a large proportion of brain volume relative to the human body?

The answer lies in the fact that a huge brain is actually a burden.

The larger the brain, the more unfavorable it is for biological predation, and it is easy to become a target for other creatures to attack, not to mention that the energy consumed by the huge brain is extremely amazing.

The human brain accounts for about 2%-3% of body weight, but the energy consumed at rest is as high as more than 25%, compared to the brain consumption of other predators, which only accounts for 5%-8%, and may be less than 10%.

Too much energy also means more opportunities for predation, which is not easy, so supplying a lot of energy to the brain will only reduce the development of other parts of the muscles.

Perhaps more than making tools, tigers and lions are better than primitive Homo sapiens, but more than fighting, there are too many creatures that can tear human ancestors to minced flesh.

Of course, the intelligence of the human brain made it easier and easier for later humans to deal with these animals, and in the 21st century, humans can easily hunt the strongest tigers and brown bears by simply pulling the trigger.

But here's the problem.

As early as 2.5 million years ago, the brain capacity of human ancestors began to increase dramatically, and even walked upright, freeing their hands and being able to use tools to throw stones and make flint knives.

But unlike what ordinary people think, even if they can make tools, human ancestors did not use tools to hunt animals, and for more than 2 million years when the brain capacity has been increasing, human ancestors have always been weak, at the edge of the food chain.

The stone tools they use are not used to hunt large animals at all, but to gather plants, dig for insects, and follow carnivores behind their backs to eat the carrion leftovers.

More than 2 million years!

For more than 2 million years, the human ancestors who were able to learn to walk were so weak and helpless, and the greatly increased brain capacity still did not bring much benefit!

This is not without examples in the evolution of nature, but it still seems strange when placed on the ancestors of human beings.

In particular, forced upright walking is not very good in the evolution of organisms, which will make the female ancestors of human beings, the hip bone narrow, the width of the birth canal limited, making childbirth a killer, not to mention that the brains of human ancestors are still getting bigger, which is even more terrifying.

There is no way, natural elimination will allow production to start "early", and many other animals can have a certain predation ability after only a few weeks of birth, and even horses can stand when they are born, or they can run after a long time.

And what about humans?

Due to the need for premature birth, the baby cannot be allowed to develop too maturely, so that from the baby to the adult, it takes eighteen years, without the rules of modern human beings, the baby is too old to have the ability to prey, and it will take seven or eight years, which is also too long and does not meet the cruel rules of nature!

But the magic scene is coming.

This weakness made it necessary for our ancestors to learn to unite, to use social skills, and to gather together to prevent being harmed by other large carnivores.

The strengthening of social skills, the further liberation of intelligence, the gathering of unity, and the birth of civilization are also promoted.

To embark on the path of civilization, it is not necessary to become stronger and stronger, but in the process of evolution, it is necessary to stimulate the weaknesses of one's own race.

If the ancestors of human beings were as powerful as tigers and brown bears, and they did not need to gather together to survive, was it possible for human civilization to be born?

So this unnatural, discordant, and strange way of evolution made the birth of human civilization possible.

It's just a possibility!

Not an inevitability!

The human ancestors who were united together gradually evolved into early Homo sapiens, but unfortunately the early Homo sapiens were still not angry, they couldn't beat lions and hyenas, tigers and leopards, and the tools they used were still to wait for the carnivores to eat them, and then divide a little leftover meat.

This has been the same for millions of years, and the same was true of early Homo sapiens, but all of a sudden, Homo sapiens entered the middle period, and there was a drastic change.

The rest of the large carnivores need millions of years to step to the top of the food chain, and this evolution is enough for nature to have time to adjust the ecological balance, no matter how strong the lion is, the faster the antelope will run, and the faster it runs, the more cooperative the hyena will be.

Nature always has a balanced capacity to regulate.

But in the middle and late stages of Homo sapiens, the situation changed abruptly.

All of a sudden, our ancestors were at the top of the food chain, catching nature off guard and leaving no time to adjust the balance of the ecosystem.

Millions of years ago, the ancestors of human beings were only weak chickens, inconspicuous in nature, and could not affect the balance of nature.

In the next 100,000 years, human beings rose rapidly, as if pulling out seedlings to help them grow, and like riding rockets, even human beings themselves could not believe that they had become the strongest species on the earth overnight, making the entire nature succumb to the feet of human beings.

If all species evolve in gambling, is there anything more exciting than human gambling?
