In fact, Mr. Cheng said that he needed to go back to a long time ago, when it was the primitive state of human beings, that is, why did our human ancestors stand up and why did they have to free up these hands?

One thing we must first confirm is that we humans are completely different from all other animals on the earth!

By the way, that's it.

Although, from a genetic perspective, primates such as monkeys have very similar genes to our humans, we are definitely completely different and have a huge gap.

There are many characteristics, such as we humans will get a disease that no animals do, that is, hemorrhoids!

That's right, hemorrhoids are the most special disease in humans. No other animals have it. The reason is that we stand up. Because we stand up, the blood circulation in that place is different. Simply put, the physiological structure there is not something that makes you stand up. If you crawl like other animals, you won't get hemorrhoids.

In fact, we humans suffer the most diseases!

Yes, our human life span is relatively long, but we humans are unhealthy. Other animals do not have so many diseases unless those animals are raised by humans, such as fat cats. As long as they are in the wild, the animals are very healthy. Once they get sick, they will die. But we humans are different. We humans will get sick or are born with illness.

By the way, we humans are all premature babies, because if we were not premature babies, we would have no way of giving birth.

Then, the second problem arises, which is why we are like this?

Mr. Cheng said that it is because we humans stand up, because we humans free up our hands to work!

Then, the key point has come, why do we have to free up our hands?

Yes, since we humans are all like this, because we have freed up our hands and become sick, then, to put it simply, according to "Evolution", this should not be worth the loss, but what is the truth?

This is necessary to start from the moment our human ancestors raised their hands and stood up from the moment they stood up on the ground!

This is an extremely important historical moment, and this historical moment is different from the times we have known in the past. We thought it was at that time on Earth millions of years ago, and our ancestors had an idea, why didn’t they have free hands and why didn’t they stand up?

Some people even say that we free up our hands to make tools because of the Stone Age.

In fact, this is all wrong, because the earliest humans had no hands and had nothing to do with making tools, and the times were not the Stone Age. There was no tools at all in that era. We humans had nothing to rely on, that was at least three million years ago!

That's right, at least, because this is an archaeological presentation. In the 21st century, humans discovered a fossil of a girl's bone in Africa, which is recognized as the place of origin of human beings. The fossil can accurately show that she was walking upright and her age was more than 30,000 years old.

This can be known very accurately. The age is made of carbon elements, and walking upright is even simpler. It depends on the shape of her bones, such as the large foot bones, arches, and spine shapes, which are all very simple and can be true.

However, more than 30,000 years ago, there were no tools. People in that era could not make any tools, so what did they do with their hands?

Finally, our human research results show that of course, there are many reasons and facts at that time, that is, the reason why humans are free of hands is not proactive, but forced!

At that time, a particularly major geographical change on the earth occurred, which was the Great Rift Valley of East Africa!

This great rift valley appeared, which directly brought about a consequence, that was, the environment in which our human ancestors lived had major changes, that is, Africa became what we later remembered, the grassland!

Originally, there were all those primitive jungles, just like the place where Yuan Fei special training was, but they suddenly turned into grasslands, which naturally brought... death.

That's right, the power of evolution comes out, and the most direct thing is the problem of Rizhao.

The sunlight is directly shining on human ancestors. Such direct emissions were not before. Many other animals were sunburned to death by such direct emissions because they could not change their habits or were too late. So what should we human ancestors do?

Stand up!

One thing that seems very simple, but it is indeed a decisive act, is to stand up and walk upright, because in this way, our human ancestors received much less sunshine and a smaller area!

At that time, this behavior was directly to ask other animals to evaluate humans...

Idiot! This is a big idiot! What are you doing when you stand up?

This is definitely the case, because this behavior is so strange that even the human race did not stand up like this, and they were still crawling.

This behavior seemed silly at the time, because it directly brought a lot of problems. What did you do with your hands?

There is also disease. After standing up, you will face the problem of having a child. If the child cannot give birth, what should I do if I have difficulty giving birth?

Giving birth to children has always been a huge problem. As far as human history is concerned, the probability of difficult childbirth is 10%, and with some other factors, the mother has always passed the gates of hell. It was not until the end of the 19th century that this problem was gradually solved to a certain extent. Later, the 20th century really increased the fertility rate on a large scale.

So, this stop costs a huge price!

But at that time, you have to stand up. If you don’t stand up, you will be sunburned to death!

This is actually a multiple-choice question, whether to be killed by the sun or stand up to endure the diseases that follow. I don’t know which one is better, but our human ancestors made this choice to stand up, and then human civilization was established. This is a decisive action!

So, since that's the case, back to that question, it is the last heir of civilization of the aliens, those individuals, who committed suicide. The reason is that, no matter how hard they try, the final result of human beings will be towards the end, and the same is true for the universe. Therefore, they committed suicide and ended their lives. There is no difference between dying early and dying late.

In this way, back to the moment when humans stood up three million years ago, will our human ancestors know that this stop will give birth to the future, like ours now, the brilliant and unparalleled human civilization?
