"Positive choice..."

"Negative choice..."

"draw."

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

The number of newborns worldwide is 380,000-390,000 every day, and a baby comes into the world every 0.24 seconds on average.

In one second, just the blink of an eye, four or five babies were born.

If the cries of newborn babies of one day are gathered together, it will be a sharp and piercing sound wave; if they all make positive, negative choices or draws, it will be an earth-shaking wave. And such a huge wave was tumbling in Gu Jun's mind.

Negative selection, draw, positive selection...

Countless young voices surged and twisted together, scratching his cortex, his neurons, and his blood vessels.

When Gu Jun, Cai Zixuan, Wang Ruoxiang and others arrived at the First People's Hospital of Dahua City, they vaguely heard the huge wave. When he walked into the isolated baby nursery, the blood vessels all over his body were swollen. But he wasn't entirely sure if he really heard it or if he was just hallucinating.

The baby's cry suddenly rang out in the nursery.

This nursery is quite spacious, with a row of incubators and related equipment placed against the wall. However, most of the current incubators are empty inside the transparent glass. Only five of them contain babies, two baby boys. Three baby girls.

One positive choice, two negative choices, and two draws.

There was another severe sting in his head. Gu Jun took a deep breath and let the oxygen supplied by the oxygen bottle in the protective suit fill his lungs and abdomen.

He breathed out again, but it didn't make his heart relax.

"Haojun?" Cai Zixuan, who was walking next to him, asked.

Wang Ruoxiang also took a look. She had a keen sense of genes during the last locust outbreak, and this time she came with a heavy responsibility.

"It's okay." Gu Jun responded, "I feel bad."

Wearing level 4 protective clothing was just a routine procedure. He had actually planned for this day, and Ulsa's cat and Elder Atal had also announced it.

Calling upon Shub-Nicholas to fight against Chaos is not without consequences.

The consequences were not just the painful loss of millions of pregnant women at that time...

Some of the words the old civet cat said rang in Gu Jun's ears again:

"That should be different from the disasters you have faced in recent years... Diseases and plagues destroy life. Shub-Nicholas does not destroy life. It reproduces life and evolves life. It is just the pressure brought by that. It would also be a disaster.”

After returning from the dreamland, Gu Jun gave the report word for word when giving a report.

So as soon as today's incident happened and was reported to the Magic Department, it immediately caused a shock.

What was going to come, came anyway.

"I think those are not scattered words, that is the words themselves." Gu Junchu made this judgment after hearing the baby's words.

Soon, emergency notifications from other countries confirmed this.

Whether it is Citi, Ross, or England, this abnormality has suddenly appeared on the five continents of the world. The difference is that they speak the local language.

But not all newborns, preliminary statistics are not average probabilities, and there are no outstanding commonalities among the population.

Some of these abnormal newborns were born to both parents, some were born to single mothers, and some were born through in vitro fertilization.

The ages of those mothers ranged from early-pregnancy girls in their teens to advanced mothers in their forties, covering almost all women's childbearing years.

All social classes and professions are not enough to mention.

From the data, it looks like it is completely random. Even if there are five pregnant women or three pregnant women in labor in the same delivery ward, there may be no abnormality in the last baby. There may be one baby, or there may be two or three.

Not only in Dahua City, but also in Dongzhou City, Mobei City and other places, such abnormal babies have appeared.

The mysterious world also appeared.

This is no accident.

"Wow wow, wow wow..." The baby girl's cry was particularly loud. She was Xu Qiuyue, the first abnormal baby born in this hospital, negative selection.

Gu Jun stood in front of the incubator, looking at the swaddled baby in the box, which was no bigger than a Zuge.

Her face was red from crying, and her wrinkled eyes had not yet opened.

"I'll call the nurse." Cai Zixuan turned around and walked away.

Gu Jun took another deep breath, remembering that the baby's father 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 on the postpartum hospital bed recuperating, unaware that the situation had escalated to the highest level. level.

Positive selection, positive selection

This is a concept of natural selection. Simply put, the mutant gene that occurs in an individual in a population makes this individual have a stronger ability to survive and a higher chance of reproduction in the environment in which it is located, so it benefits and has more The mutant gene spread among the descendants of the population.

This is called positive selection.

negative selection, negative selection

Contrary to positive selection, individual mutant genes are not suitable for the environment in which they live, and those that harm survival ability and reduce reproductive opportunities will be naturally eliminated.

In the long history of human evolution, there must have been

More and more different genes have been discovered, causing various diseases, defects, and weirdness, but they have not been passed down in the human gene pool because they died young, died young, and had no offspring.

This is called negative selection.

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

edar370a is a gene unique to most East Asians. One of its effects is that the density of sweat glands in the human body is 15 higher than that of other races, making it particularly easy to sweat. The other is that it causes hair to be denser and straighter, without the natural curls.

Because this mutation had a survival advantage in adapting to the environment in ancient times, it was positive selection.

But if you put edar370a in a desert environment that is hot all year round, it will be a negative selection.

Because sweating easily means that the body's water will be lost faster and more. In places where water sources are scarce, not sweating easily is the right choice.

During the Little Ice Age, diabetes-causing genes were under positive selection, because high blood sugar has an anti-freezing effect, giving them a greater chance of survival. You must know that the average life span of people in the Little Ice Age was much shorter than the average life span of people who died of diabetes.

In modern times, this gene is subject to negative selection. If the world suddenly freezes, this gene will become a positive selection again.

Therefore, the mutant gene itself has no positive or negative distinction. It is the environment that determines the positive and negative. The fittest survive and the unfit are eliminated.

The environment is always changing, so the genes of a group must be diverse.

Even some seemingly useless and harmful genes are still with humans. They may have been the best survival strategy once, or maybe one day, they suddenly became the best strategy.

Positive selection is not always inherited, there is no particular advantage or loss, it is balanced selection.

Positive selection, negative selection, draw

What is the decision based on now? It exists in every environment around the world. Is this an era where the dark power has reached a new peak...

Gu Jun noticed that among the five abnormal babies in the nursery, the two tie babies were sleeping quietly.

The baby who was choosing had already opened a pair of big dark eyes, turned around, and seemed to be looking at the world curiously.

The two negative selection babies were crying non-stop and seemed very uncomfortable.

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

Gu Jun also saw that the eyes of the negative choice baby named Xu Qiuyue were opening. The time for a newborn's eyes to open varies from person to person, ranging from birth to one week.

He didn't know why, but looking at the two wrinkled eye slits, he felt panic rising in his heart.

Suddenly, the little baby girl opened her eyes while crying.

The new-born eyes were all white and had no pupils.

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

Negative selection.
