Homo sapiens.

The ever-increasing knowledge base and the long learning time will cause the speed of human development to decline again.

Although the new human beings at this stage have not experienced a decline in their development speed, this situation will inevitably occur in the future.

When there is too much knowledge to learn, it is when the development of new human beings enters a bottleneck period.

Li Qingye is planning for a rainy day. He intends to use the power of genes to record knowledge into genes, and then allow human beings to directly inherit the knowledge in genetic memory after completing physical development, thereby breaking the development bottleneck.

Chapter 551

In a private laboratory.

Li Qingye used the genetic memory input device to input the prepared relevant knowledge into the genes of the experimental cells bit by bit.

The principle of this genetic memory input device is actually a derivative technology researched after figuring out how genes memorize data.

More than a dozen related laboratories have researched genetic coding technology, decoding technology and input technology.

However, compared with genetic memory decoding technology, genetic memory recording technology still has some problems.

For example, the problem Li Qingye encountered in front of him.

Several assistants are operating the device, but the content is only 10G, and the input speed is as slow as a turtle crawling.

When Li Qingye saw the progress bar for this year on the screen, he didn't look anxious, because it was within his expectation.

Genetic memory entry and brain cell interaction through biochips are two different modes.

The principle of interaction between biochips and brain cells is based on the transmission of brain waves and neuron signals, which are fast, fuzzy, and forgettable.

The genetic memory entry will change a part of the gene sequence, which is fundamentally entered, and will basically not be forgotten, unless the gene sequence responsible for recording information is destroyed.

Li Qingye called this gene responsible for recording information "memory gene".

Typically, these memory genes are placed among recessive genes in the genetic sequence.

In fact, human beings, like many animals and plants, have a large part of their genes seemingly useless. These genes generally have no effect in the human body.

However, after a lot of research by the researchers of Homo sapiens, the basic situation of human genes has been figured out.

Human genes can be divided into dominant genes and recessive genes, the proportions of which are 35%-37% and 63%-65% respectively.

Among them, the vast majority of memory genes are recessive genes, which are memory genes of dominant genes, accounting for only about 3-9%.

This phenomenon causes humans to have an inexplicable fear of some animals or objects.

In fact, this is the embodiment of a small part of ancestral memory in ancient times, which is in an activated state.

Humans are relatively weak in this regard.

In other animals, such as elephants, migratory birds, and whales, more of their memory genes are in a dominant state, so they can acquire more memories.

In fact, this is an evolutionary choice.

The reason why humans abandon the inheritance of this genetic memory is that humans have developed language.

Although animals have a simple sound communication mechanism, it is difficult for them to pass on a lot of information to the next generation through sound, and they can only pass on genetic memory.

Both have advantages and disadvantages.

The advantage of genetic memory inheritance is that the knowledge is fixed, and it does not need to be taught by hand, which increases the survival rate of the cubs; the disadvantage is that the genetic memory is not 100%, there will be memory loss, and the genetic memory will form an instinctive reaction, and it can only be inherited in one continuous line , In addition, the information of inherited memory is also very limited.

The advantage of language and text inheritance is that the information density is relatively high, the information carrier can be separated from the organism itself, and can be passed on to many; Education, the survival rate is too low, even if they barely survive, they will degenerate into savages.

The inheritance of genetic memory that Li Qingye wants is not the primitive model of animals, but to get rid of some shortcomings.

For example, the information density is too small, the memory is lost, the memory is fuzzy, and the input speed is too slow.

"Chairman, the entry is complete."

Li Qingye glanced at the time, and it took 3 hours and 24 minutes to input 10G data into the memory gene. He shook his head: "It's too slow, it seems that the input method must be improved."

As for why not use the interactive communication method of biochips and brain cells to record information into memory genes.

The reason is very simple, because the memory of biological brain cells will not be 100% included in the memory gene, which is fuzzy memory.

In the final analysis, this situation is caused by the brain's self-protection mechanism.

Most of the memories in human life will be forgotten, and only those profound contents can be recorded.

Li Qingye has activated the memories of his ancestors, and he is very clear about this.

In the memory of his ancestors, only the important content will remain in the memory.

And something similar to eating a bowl of rice today and drinking an extra glass of water yesterday, there is a high probability that it will not be entered by the memory gene.

Unless it is on the verge of death because there is no water to drink, the memory gene will enter this information.

Based on his own situation, Li Qingye concluded a rule, that is, the more life-threatening content, the more it will be recorded in the memory gene, and the more trivial things, the less it will be recorded.

Why do humans generally feel uncomfortable when they see snakes?

It is because in ancient times, human ancestors saw their companions being bitten to death by poisonous snakes. This kind of horror between life and death will stimulate the brain cells of the survivors, allowing this memory to be engraved into the genes.

And this key memory and forgetting mechanism made Li Qingye's work of accurately entering information very difficult.

The modern knowledge system is very large and interlocking, especially the knowledge in the field of science.

If the entered information is inaccurate, and there are still gaps, it will cause the host to fail to form a complete knowledge system after activating the memory gene, and must re-learn and check for omissions.

Li Qingye looked at the newly decoded report and entered 10G of data, but only 1.3G of the decoded information was accurate, and the rest was a lot of garbled codes and invalid data.

13% accuracy, this cannot guarantee inheritance at all.

Until the accuracy reaches 99%, there is no way for this technology to be put into application.

After all, literary works, music, etc., if they lack some content, they can barely be used.

But the lack of 1% of scientific knowledge is a very serious problem.

Science must be rigorous and precise, which is a hard requirement.

However, there is a certain degree of uncertainty in the entry of memory genes.

Now Li Qingye is troubled by this problem.

Putting down the report, he picked up the teacup and took a sip of green tea.

The bitter fragrance calmed him down a little.

He put down his teacup, leaned back on the chair, and sighed softly: "Things like memory and genes are indeed the most difficult to deal with."

Sanjibada Leyal quickly rubbed his shoulders.

Other assistants continued to work hard, looking at various experimental data.

Suddenly the laboratory door opened slowly, and a middle-aged man in gray-white protective clothing walked in, and reported to Li Qingyehui respectfully:

"Chairman, there is a problem in the forest of Pan Gu Realm. This is the investigation report."

Li Qingye frowned, took the tablet, he flipped through a few pages, and then a surprised expression appeared on his face: "It seems that the effect of environmental pressure is unexpectedly good!"

"Chairman, do you want manual intervention?" The middle-aged man asked quickly.

Li Qingye thought for a while: "Intervene? No, continue to observe, as long as the defense system is not threatened, continue to let it develop naturally."

"I understand." The middle-aged man nodded.

However, Li Qingye still added: "After you go back, let the people in the security department make a targeted plan."

"Yes."

Chapter 552 Super Evolution

After the middle-aged man returned to his office, he immediately summoned the person in charge of the security department.

"Olaer, the chairman asks you to formulate a response plan for this thing, just in case."

Olaer, who was in charge of the security work in Pan Gu Realm, picked up the tablet computer and carefully browsed the contents.

The above describes a new species that has recently been mutated - the nuclear cockroach.

This thing is not a good thing just by its name.

The nuclear cockroach is about the same size as the American cockroach, and it lives in symbiosis with the discharge bacteria. The wings on its back have completely degenerated and become a rucksack that stores special substances.

Inside the rucksack are enriched radioactive elements, mainly carbon-14.

This is where the nuclear cockroach gets its name from.

If that's all it is, the nuclear cockroach is not qualified to let the middle-aged man report to Li Qingye.

The reason why nuclear cockroaches have attracted much attention is their unique biological structure and way of living.

We must know that carbon-14 is a radioactive substance, and the concentration of carbon-14 enriched by nuclear cockroaches is about 0.82%, and the radiation dose is not optimistic.

So how did the nuclear cockroach survive under such circumstances?

The reason they survive is that when they eat, the food will stay in a special digestive tract organ. In this organ, radioactive substances will be enriched into the backpack on the back.

The radioactive material enriched in the rucksack, the high-energy rays it produces will be absorbed by the symbiotic discharge bacteria, and then generate electricity and heat to supply the bacteria and cockroaches.

Swarms of nuclear cockroaches can threaten animals such as feral dogs and cats because of their joint discharges that can kill animals hundreds of times their size.

In addition, data obtained through the monitoring room shows that these cockroaches, like their relatives termites, have evolved female insects.

The female worm of the nuclear cockroach can lay about 500 eggs every day, which makes the population of the nuclear cockroach continue to expand, and has occupied 24% of the southern jungle of the Pangu Realm.

……

After reading the relevant report on the nuclear cockroach, Olaer finally understood the danger of this creature, and he replied seriously: "Manager Lin, please rest assured, I will definitely prepare relevant countermeasures."

The middle-aged man Lin Haibin nodded: "Then I'll leave it to you."

"You're welcome, this is my job."

After Olaer left, Lin Haibin immediately got up and went to another area.

Once he's here, he's confronted with the return of the robot who just captured the Nuka cockroach.

Looking at the dozens of nuclear cockroaches that were cryogenically frozen in the storage container, Lin Haibin instructed Tai Muxin, the leader of the scientific research team:

"Muxin, you have to make arrangements, don't let these nuclear cockroaches escape, or the consequences will be very serious."

Tai Muxin also attaches great importance to this matter. As a biologist, does he know that the genetically recombined and mutated creatures in the Pangu world are too dangerous because there is no gene lock.

If accidentally leaked into the natural world, it has the potential to cause terrible damage.

In fact, without Lin Haibin's reminder, Tai Muxin has already attached great importance to it. He replied cautiously: "I will pay attention to this issue. Does Manager Lin have anything else to do?"

"Well, I came to your place because the chairman asked me to strengthen security measures just now, so I came to your place to inspect."

"I see, do you need me to lead the way?"

Lin Haibin shook his head: "No, I need an independent investigation. You are insiders, and you may not be aware of any abnormalities inside."

"That's fine, then I won't bother you." Tai Muxin turned around and was busy with his own affairs.

Lin Haibin and his assistants carefully inspected this area.

……

Under the protection of comprehensive protective clothing, Tai Muxin and several researchers carefully observed the slices of nuclear cockroaches through the electron microscope.

Another researcher came over with a genetic test report.

"Head, the genetic test results of the nuclear cockroach are out."

Tai Muxin asked without raising his head: "How is the situation?"

"Compared to a week ago, there are 23 more gene mutations."

Tai Muxin was not surprised at all: "In a high-radiation environment, the probability of gene mutation is indeed very high, and insects can withstand it."

At this time, the radiation dose inside the Pangea world was about 50 times that of the normal environment on the earth's surface. Many mammals living in the Pangea world were either killed by radiation or contracted various diseases.

As for the two mammals, wild boar and mouse, they can survive tenaciously in this environment and are gradually adapting to the environment.

Other wild dogs, wild cats, cattle and sheep have basically been wiped out.

Insects and microbial plants are the most resistant to radiation.

Rats and wild boars can survive because they have rough skin and thick flesh, and they can produce a lot of them in one litter, which greatly increases the survival rate.

If it is replaced by a natural person, when the radiation dose suddenly soars 50 times, then the natural person will most likely be finished, even if the group size is several hundred million, it is useless.
