Chapter 508

"Positive choice..."

"Negative selection..."

"Draw."

Positive choice, negative choice, draw, negative choice, draw, positive choice, positive choice, draw, draw, negative choice, draw, negative choice

There are 380000-390000 newborns per day in the world, with an average of 0.24 seconds.

In a second, it's just a blink of an eye, and four or five babies are born.

If the cries of newborn babies are gathered together, it will be a sharp sound wave; if they all make positive and negative choices or draw, it will be a huge wave. And such a huge wave is tossing in Gu Jun's mind.

Negative choice, draw, positive choice

Innumerable young sounds, rolling and twisting together, scraping his cortex, his neurons, his blood vessels.

Gu Jun, Cai Zixuan, Wang Ruoxiang and other people came to the first people's Hospital of Dahua city. They heard the huge wave faintly. Then they walked into the isolated baby care room, and his blood vessels were swelling. But he's not entirely sure that he actually heard it, or that he was just hallucinating.

The cry of the baby suddenly rang, which was heard in this nursery.

This nursery room is quite spacious. There are a row of incubators and related equipment against the wall. However, most of the incubators are empty in the transparent glass. Only five of them contain babies, two boys and three girls.

One positive choice, two negative choices, two draws.

His head was a sharp pain again. Gu took a deep breath and filled his lungs and abdomen with oxygen from the oxygen bottle in his protective clothing.

He exhaled again, but it didn't relax his heart.

"Hao Jun?" Cai Zixuan, who was walking beside him, asked.

Wang Ruoxiang also looked at it. She had a keen sense of smell for genes in the last locust disease, and this time she came with a heavy responsibility.

"Not bad." Gu Jun should say, "the heart is not good."

Wearing level 4 protective clothing is just a routine procedure. In fact, he had anticipated this day. UZA's cat and elder artar also had notices.

Calling on Shab Nicholas to fight against chaos is not without consequences.

The consequences are not just the painful loss of millions of pregnant women who miscarried at that time

Gu Jun's ears were echoed by the old civet cat again:

"it should be different from the disasters you have faced in recent years Diseases and pestilence are meant to destroy life. SAB Nicholas does not destroy life. It breeds life and evolves life. It will bring heavy pressure, and it will also be a disaster. "

After returning from dreamland before, Gu Jun handed in the original words word for word when giving a report.

So as soon as today's event happened, it was reported to the incantation department, which immediately caused a shock.

Come, or come.

"I don't think it's a fragmented discourse, it's the discourse itself." Gu junchu listened to the baby's words and had this judgment.

And soon, emergency reports from other countries confirmed this.

Whether it's Citigroup, Russia, Britain, or five continents all over the world, the difference is that they speak the local language.

But not all newborns, the preliminary statistics are not the average probability, and there is no prominent common ground of the population.

These abnormal newborns are both parents, there are single mothers, and test tube baby surrogacy.

Those mothers range in age from teenage early pregnant girls to older mothers in their 40s, almost all over women's childbearing age.

All social strata and occupations are not enough.

From the data, it looks like it's completely random. Even if there are five or three pregnant women in the same maternity ward, there may be no abnormality in the last baby. There may be one or two or three of them.

Not only Dahua City, but also Dongzhou City, Mobei city and other places, there are such abnormal babies.

The mysterious world also appeared.

This is not an accident.

"Whoa, whoa, whoa..." That baby girl's cry is particularly loud, she is Xu Qiuyue, the first abnormal baby born in this hospital, negative selection.

Gu Jun stood in front of the incubator, looking at the baby in the box, not bigger than a Zuge.

Her face was red with tears and her wrinkled eyes were still open.

"I'll call the nurse." Cai Zixuan went back.

Gu Jun once again took a deep breath. He remembered that the father of the baby was so excited that he almost knelt on the ground and begged them to save his daughter, while the baby's mother was still lying in the hospital bed after childbirth. It was not clear that the situation had escalated to the highest level.

Positive selection is a concept of natural selection. To put it simply, a mutated gene in an individual of an ethnic group has a stronger survival ability and a higher chance of reproduction in the environment in which it is located. Therefore, more offspring will be benefited from it. This mutant gene will spread in the population.This is called positive selection.

Negative selection, negative selection

contrary to positive selection, the mutant gene of an individual is not suitable for the environment, which will damage the survival ability and reduce the reproductive opportunity, and will be naturally eliminated.

In the long history of human evolution, there must have been more and more different genes, which have led to various diseases, defects and weirdness, but they have not been passed down in the human gene pool because of premature death, premature death and no offspring.

This is called negative selection.

However, whether a mutated gene is a positive or negative selection is not absolute, but depends on the environment.

Edar370a is a unique gene in most East Asian people. One of its functions is that the density of sweat glands in human body is 15% higher than that in other races, which is particularly prone to sweating; the other is that the hair is denser and straighter, and there is no natural curl.

Because this mutation has the survival advantage of adapting to the environment in ancient times, it is a positive choice.

But if you put edar370a in a hot desert environment for a long time, it is a negative choice.

Because easy sweating means that the body's water will be lost faster and more, in the lack of water, not easy to sweat is the right choice.

In the little ice age, the pathogenic gene of diabetes is a positive choice, because hyperglycemia has the effect of anti freezing, so as to get a greater chance of survival. We should know that the average life span in the little ice age is much shorter than that in the case of diabetes.

In modern times, this gene is negative selection. If the world were suddenly frozen, the gene would be a positive choice again.

Therefore, there is no difference between positive and negative mutation genes. It is the environment that determines the positive and negative. The fittest survive and the unfit are eliminated.

The environment is changing all the time, so there should be diversity in the genes of a population.

Even some seemingly useless and harmful genes are still with us. They may have been the best strategies for survival, or they may one day suddenly become the best strategies.

It is not always a positive selection to inherit, and there is no special advantage or failure, that is, balanced selection.

Positive choice, negative choice and draw

what is the decision now? Is there a new era of active global environment

Gu Jun noticed that among the five abnormal babies in the nursery, the two tied babies fell asleep quietly.

The baby, who is choosing, has opened a pair of big black lacquer eyes and looks at the world curiously.

And the two negative selection babies, both crying all the time, seem to be very uncomfortable.

At this time, Wang Ruoxiang reminded: "Xu Qiuyue seems to be opening her eyes..."

Gu Jun also saw that Xu Qiuyue's eyes were opening. Eye opening time varies from person to person, from birth to a week.

Don't know why, he looked at the two wrinkled eyes, his heart filled with panic.

Suddenly, the baby girl opened her eyes in tears.

That pair of new eyes, all white, no pupil.

That is, there is no lens, all vitreous body, all vitreous body

Negative selection.
