Chen Yun said, "First of all, ancient Homo sapiens walked on all fours, and their hands could not only act as legs and feet, but also stand on both legs when facing enemies, freeing up their hands to fight wild beasts. After human beings are accustomed to walking upright, they do not have the habit of exercising their hands, resulting in muscular legs, but the strength of their arms is very weak, and their combat ability is sharply reduced. ”

This is a fact, I have to admit that the species that often keep walking on all fours, the arms can be exercised all the time, so the fighting ability is also very strong, and human beings have since the liberation of their hands, physical fitness has begun to decline significantly, which is the root of the disease accumulated by tens of millions of years of genes, even if today's human beings no matter how they exercise, it is difficult to have the explosive power of ancient Homo sapiens, not because the exercise method is unscientific, but limited by genetic limitations.

Then Chen Yun elaborated on the second point, saying that the human skeleton structure has not yet evolved completely, and is not suitable for long-term standing and sitting postures, and the human lumbar spine has been concentrated in the waist since it has been straightened, so that the bones have been subjected to the weight of the upper limbs all year round, so the bones of modern people often have lesions, such as lumbar disc herniation, frozen shoulder, which is also a problem formed after humans learn to stand.

This argument has been well explained in Ge Zhuang, this fat guy weighs too much, and the pressure on the lumbar spine is also great, so there will always be low back pain when it rains on a cloudy day.

"And then there's the fact that human reproduction has been greatly affected." Chen Yun continued, "Humans learn to stand, resulting in a smaller female pelvis, most of the animal cubs can have the ability to eat after leaving the mother, most of the animal's offspring learn to walk after a few hours of sounding, but human babies can't, not only can't chew, even teeth don't grow, or even crawl, so survival skills are learned through imitation and exercise." ”

I say what does this prove?

Chen Yun said that this proves that human fertility is declining, and every newborn baby is a premature baby, in order to adapt to the narrowing of the human hip bone, so we will only experience ten months of pregnancy, and the baby who has not yet matured will be expelled from the body, if the baby continues to develop in the mother's body, it will cause dystocia. The consequence of the narrowing of the human hip bone directly increases the difficulty of the mother giving birth to a baby, and since ancient times, a woman's birth to a child has been an extremely painful process, and this pain comes from the evolution of human beings.

In ancient times, when Homo sapiens were not yet used to walking upright, it was not so difficult to give birth to babies from a pelvis that had not yet narrowed. They give birth to babies that are stronger, longer and more mature.

After listening to Chen Yun's narration, I nodded, according to what you said, whether human beings have become what they are today, whether it is progress or the regression of racial genes, it is also debatable, and it is almost the same as changing "Theory of Evolution" to "Theory of Degradation".

Chen Yun continued, "Evolution is to better adapt to the environment, and human beings seem to be gradually losing this ability, out of cities and densely populated places, many people have difficulty living in nature, unable to adapt to the harsh ecological environment, and it is also because of this so-called 'evolution'." ”

Ge Zhuang smiled and spoke, "Isn't it better to go in and out of a building, and you can take a car when you go out, what do you need so much extra physical strength for?"

Chen Yun said, "I'm not saying that this status quo is bad, I just think it's strange, think about it, if you follow the principles of evolution, the evolutionary direction of most organisms is more and more towards the direction of robustness and health, but human beings are an exception, we are not only changing, but also becoming more and more fragile, what is the source of this genetic decline?" ”

She added that if this evolutionary direction continues, I am afraid that in tens of thousands of years, human beings will only have a spherical shape, because there is no need to walk at all, and there is a car to replace it, so there is no need for legs to exist, and with the progress of biological science, the technology of IVF has become more and more mature, and human beings no longer need reproductive organs, and they only need to use instruments and equipment to give birth to children......

I hurriedly asked her to stop, I couldn't imagine what the hell would become if human beings really developed to that point, and said with a wry smile that this is not a topic we should worry about, life can be passed, and it is unknown whether human beings will survive until that day.

Chen Yun said that this is the problem I am most worried about, human beings can no longer survive in the natural environment without technology, and technology is a double-edged sword, which can not only meet the enjoyment of human beings, but also bring human extinction from the roots, maybe human wisdom, will eventually lead to self-destruction.

"Alright, that's the end of the conversation, look, those toads seem to be moving!" At this moment, the old clock suddenly came up and reminded us not to waste time on this kind of empty theory.

We hurriedly turned our eyes to the crater, and sure enough, we saw a large number of giant toads commotion, especially the part of the toads on the edge of the volcano, as if frightened, were trying to leave the crater, and a large group of toads were frantically running towards the foot of the mountain.

"What's going on?" The ears were filled with a large "quack" cry, and the panicked output gate was frantically shaking its fat body, shattering many fossils, rolling down the crater, while the volcano, which had been silent for thousands of years, began to faintly begin to stir, with even hotter air currents diffusing out, forming puffs of black smoke, and the air was filled with a strong smell of sulfide.

"Oops, it's really not a coincidence, could it be that the volcano has been calm for tens of thousands of years, and it is about to start erupting again?" Ge Zhuang hurriedly stood up and shouted wildly.

My heart is also sinking, the underground space is in a semi-closed state, if the magma erupts at this time, even if my parents regenerate two legs, they can't run, do they have to die here?

The sudden vibration in the mouth of the magma made everyone nervous, and I could clearly perceive the tremor of the ground, and the countless piled fossils around me were also affected by this tremor, and many bones that had already dried also erupted into a collective "click" sound, and the bones were constantly exploding, turning into rock powder and rolling down.

The kettle in my footsteps "grunted" for a moment, and suddenly I noticed that it was rolling down the slope, but I didn't bother to pick it up, and I saw that the fossil layer around me was gradually collapsing, and the stones were peeling off, turning into gravel and rolling down, and the blazing waves tumbling in the magma flow became more and more crazy, and my expression turned blue little by little.

"Run!" Ge Zhuang didn't even bother to pick up the equipment, turned around and dragged me down the mountain, I dragged him and shook his head, "Fatty, if it really erupts, it won't work if you put two motors on your buttocks, save it, I guess this magma may not be able to erupt." ”

When the two of us were talking, Chen Yun took the initiative to stand up and slowly walked towards the restless magma mouth, the billowing smoke in the crack of the magma was accompanied by the scorching temperature, and even the air was about to be roasted and distorted, I put Chen Yun stupidly to the side, and hurriedly ran over to drag her, "What are you doing, don't go near there, it's dangerous!" ”

Chen Yun shook off my hand and said, "Don't worry, it's okay, it's not magma restlessness, it seems that someone touched the mechanism below, it won't be like this before the volcano erupts." ”
