Chapter 386 The road to life transformation caused by a drop of rain
The emergence of a high-concentration oxygen environment will not only bring about mass extinction of species.
Various lighting conditions, seasonal changes, air humidity, air temperature, the fragmentation and reorganization of food chains and food webs, etc., will all change together. And this complex linkage change is not just one time.

Later, when Wang Wutian himself took the opportunity to comprehend the mystery of the laws of space.
A hint of understanding flashed in his eyes.
"My whole body's bones have begun to break and reshape, and they are undergoing all-round structural optimization and completion."
He once again felt that the bones all over his body began to itch and heat violently, and at the same time there were continuous "click-click" sounds coming from his body, like the sound of bones being broken.
Separate a ray of spiritual thought and sweep it gently.
"Is this the secret of the Bone Strength Realm?!"
As a knowledgeable founder.
He deeply understood that human beings' own skeletal structure had many serious flaws and its mechanical properties were very poor.
A single load-bearing vertebrae will become distorted, that is, it will become an S-shaped structure. As a result, the vertebrae will become very vulnerable to damage.
Apart from these shortcomings.
Such a vertebral structure also causes the upper limit of human skeleton height to never exceed three meters.
Once this height value is exceeded.
Not only is the structure of the spine extremely poor, but the center of gravity shift is serious, which is why the S-shaped body shape appears, with lordosis and backwardness. This is true for both men and women in their skeletal structure.
From the perspective of human beings' own aesthetics.
The S-shaped figure with bulging front and back looks beautiful and full of sex appeal, but in fact, it is just an intuitive external manifestation of serious defects in the body's spine and bone structure.
And the body has to adapt to the shift in the center of gravity.
The human body's own mass and the falling gravity generated by the current planet's gravity will break and crush the vertebrae.
At that time, it can range from half-body paralysis or full-body paralysis, to severe death.
This is just a serious flaw in the spine.
There is also a special pelvic structure unique to the female gender.
The complex skeletal structure related to the pelvis has extremely limited expansion when giving birth to offspring. As a result, not only does the pelvis have to endure intense labor pains when giving birth.
It will also seriously affect the fetal skull bone development.
In order to ensure that the fetus can be successfully born.
Another example is the reproductive bones that are only found in the male gender. The disappearance of the reproductive bones makes it impossible for men to shrink their penis into the abdomen, thus completely exposing their fatal weakness.
Not only is it very easy to get injured.
It is also very prone to various reproductive diseases, which can lead to problems in reproducing offspring.
The bones related to the pelvis are difficult to expand greatly. The related genes of the fetus will lock the skull in an undeveloped state on its own, and it will gradually continue to develop slowly after birth.
This not only greatly affects the natural competitiveness of future generations, but also increases the mortality rate of infants and young children.
The skull bones are not fully developed.
This means that the brain is in an extremely fragile and vulnerable state. A slight collision will cause damage to the brain, which will directly affect a lifetime.
There are also defects in the maxillary and mandibular bones.
This causes functional degeneration of the teeth growing on the gums of the upper and lower jaws, seriously weakening the natural competitiveness.
Unable to continue eating the most nutritious raw meat.
In order to survive.
That's why mankind, under the pressure of life and death, was forced to learn to use flames to make cooked food with less nutrients.
However, because the nutrients contained in cooked food are even rarer and are severely lost during production, humans have to eat several meals of cooked food every day to maintain their normal cell life activities.
Not like other animals.
in nature.
Hunting competition between different species is extremely cruel.
In order to ensure their strong survival competitiveness, animals reduce the number of hunts and improve energy absorption and utilization, so they all eat raw meat, because raw meat contains the most nutrients.
The emergence of skeletal defects in humans has weakened their natural competitiveness.
A full meal of raw meat can last for several days, more than ten days, months, or even years, without wasting time eating again.
Such changes in bone defects.
This is tantamount to setting yourself up for trouble, doing yourself a disservice, and adding many negative weaknesses.
He has locked up his most flexible body structure.
Not only that.
This combination of the most flexible bone part and the stiffest bone structure also makes the kneecaps of human legs extremely vulnerable to damage.
Once damaged, humans' own athletic ability will plummet.
A further impact is that because humans began to eat cooked food, their physical fitness became worse and worse, making it increasingly difficult to compete with animals in physical fitness, and their resistance to various diseases and viruses was further weakened.
Then in order to survive, human beings are forced to figure out how to cure diseases.
…
…
In addition to these bone defects that are easily overlooked by ordinary people.
The leg bones and kneecaps of human beings also have serious defects, which are no less serious than the natural defects of the spine.
among all human bones.
The bone with the most delicate and complex structure and function is the kneecap.
But it happens to be the most delicate, complex and flexible bone structure, which is connected one behind the other, the femur and tibia, which have the least mobility, two bones like straight wooden sticks.
Or unable to move, directly paralyzed.
Look at how rigid and rigid the skeletal mobility of human beings is, and compare it with the skeletal mobility of domestic cats. It is incredible how flexible and flexible, fast and agile it is.
It's like the ability to shrink bones.
The two are not on the same level at all, and human beings are completely crushed.
"But now, I have reached the level of Bone Strengthening, and I have begun to spontaneously adjust and optimize this method, which has many serious flaws."
"Large bones are splitting into more small bones, and the overall structure is becoming more refined."
"And more bones are being regenerated."
From this we can roughly judge how serious this congenital bone defect is and how useless the human bone structure is.
…
…
"There are really too many defects in human bone structure." Wang Wutian looked at himself and said silently: "My previous bone structure has not changed much, and I am still the same as a human being."
"There are flaws and weaknesses everywhere."
He already has a very clear guess in his mind about how the Bone-Strengthening Realm will evolve next.
The number of bones in a newborn baby is 305.
The number of bones in a young child is 217 to 218.
When the human body begins to grow and develop, the number of bones in the whole body is only 206.
As age gradually increases, the total number of bones in the body decreases. The consequence of this is that the body's own movement ability and body flexibility become weaker and worse.
