At noon that day, the No. 1 canteen in Kunlun Park.

According to the planning of the park, there must be five canteens in the entire Kunlun Park, but so far the number of staff in the park is not large, and only this No. 1 canteen has been used.

The master of the No. 1 canteen is Zhou Lingshi, and his wife Wang Jinhua gives him a hand.

There is a weekly spoon, and the food level is naturally very good. Dean-level tasks like Cao Yusheng and Yang Tuo, in addition to the normal work package, Zhou Lingshi will also add two dishes to them and let Wang Jinhua bring them to the box.

The location of this box is relatively partial, and the sound insulation is also good, Cao Yusheng and Yang Tuo are used to eating here, and they can communicate with each other at noon and share the front line and progress.

At this table at noon today, there are more people than usual, and Miao Guangqi and He Zihong are also there.

In this way, the seven-member decision-making team of the Kunlun plan, four of which were present.

Among these four people, Cao Yusheng, as one of the deputy team leaders, is responsible for coordinating the rear work.

The old mastermind naturally knew about the nest and was also waiting for the results of the research institute.

At this moment, when he saw the state of the three people, he vaguely knew it in his heart.

The two old and one small, their faces were a little blue, and their eyes were bloodshot, and it seemed that they had stayed up all night last night.

And there is no joy on the face, indicating that the progress is slow, and there is no result for the time being.

So Cao Yusheng was a little strange, and said to Miao Guangqi: "In this world, there are still things that can stump you?"

Miao Guangqi rolled his eyes: "Nonsense, if there is nothing in this world that can be difficult to stop me, Lin Shuo should be my son now." ”

"That's not right for you. Cao Yusheng smiled slightly, "My wife may be someone else's good, my son must be my own good, and Miao Chengyun is not bad." ”

"Alright, I'm not in the mood to laugh with you right now. Miao Guangqi had some impatience on his face, and then said to Yang Tuo, "Xiao Yang, do you have any ideas for yourself?"

Yang Tuomeng picked up the rice and turned a deaf ear to Miao Guangqi's question.

Miao Guangqi looked a little stunned, and then glanced at He Zihong.

He Zihong hurriedly said: "This kid is like this when he is focused, he doesn't pay much attention to people, and it will be good to wait for the result." ”

"That looks like we'll have to wait a while. Miao Guangqi shook his head.

"It's not Lao Miao, listen to what you mean......" Cao Yusheng frowned, "Is it not a clue at all?"

"I can't talk to you as a layman. Miao Guangqi said with a disgusted face, "Scientific research work, it is first of all to discover the objective laws of things.

It is absolutely rational and also requires absolute objectivity.

It's not like we want to get what we want, and we just go here and get it.

It's the other way around, what we find in it, and then we figure out how to apply it.

Of course, it is not pure luck, there will be assumptions in advance.

This assumption is often a self-consistent mathematical model, or a number of years of observational data, which exists as a theoretical guide for experiments.

However, in the course of experiments, these theories may be overturned, which requires scientists to find new laws and verify them through experiments......"

"It's rambling. Cao Yusheng waved his hand impatiently, "Speaking of people, where are you stuck at the moment?"

"Isn't this stuck in the fact that the previous theories have been overturned, and the new laws have not yet been found. Miao Guangqi spread his hands.

"No, your biological research is not physical research, where is the mathematical model?" Cao Yusheng said, "Isn't it all hypothesis? It's not normal for a hypothesis to be overturned, so why don't you put forward a new hypothesis?" ”

The hypothesis is also a summary of laws based on experimental observations, and the basic logic is self-consistent. Miao Guangqi said, "At present, the establishment of human biology is based on the research findings of our biological evolutionary branch. Our evolutionary branch, going up billions of years, our ancestors called 'Luca', have you heard of it?"

Cao Yusheng shook his head, and then said, "I know 'Lucy'." ”

"Lucina is an East African hominid, the ancestor of mankind. Miao Guangqi said, "I'm talking about 'Luca', which is a rock cell. ”

"Rock cells?"

"Yes, there are many hypotheses about the origin of life, but in my opinion, the most plausible one is the black chimney under the sea. "Near the Galapagos Islands in the middle of the Pacific Ocean, there is a rift valley on the ocean floor, and there is this black chimney at the bottom of the rift valley.

The so-called black chimney is actually a volcanic crater located at the bottom of the sea.

The billowing black smoke from the black chimney is the result of sulfide being squeezed into high-pressure seawater from the inside of the volcano.

Unlike an ecosystem on the ground, which is powered by sunlight, this is an ecosystem that is powered purely by geothermal energy.

Those sulfides are the nutrients for the life around us.

The material emitted by the submarine volcano is cooled by high-pressure seawater and instantly solidifies into a loose substance, which is covered with small cavities less than 100 microns in diameter.

This pore size is roughly equivalent to that of a cell.

Based on the above observations, the hypothesis of the biological origin of the submarine black chimney is born.

More than four billion years ago, the Earth was still an ocean, and there were countless such black chimneys at the bottom of the sea.

Some volcanic eruptions are strongly alkaline, and the water tends to be acidic.

Between the acid and alkali, there is a layer of rock that can slowly penetrate the material, which allows the energy brought by the acid-base neutralization reaction to be released in an orderly manner.

This delicate chemical energy gives rise to organic matter in the small cavities of those chimney stone walls.

Then, over a long period of time and hundreds of millions of rocky cell environments, RNA and DNA were synthesized successively, began to replicate and spread themselves, and our ancestor 'Luca' was born.

Until now, the form of energy on which the core chemical reaction of our human metabolism, the 'tricarboxylic acid cycle', depends, is this delicate acid-base neutralization reaction.

This is the configuration at the bottom of our evolutionary branch, which was already decided when our ancestors were still rock cells.

It is also the upper limit of the energy used by our human beings, the chemical energy brought by the acid-base neutralization reaction, the so-called end of human cultivation, this is the ultimate shackle. ”

"Hey, this is the first time I've heard of it. Cao Yusheng shook his head, "Then what? What is the problem you are facing now?"

Miao Guangqi ignored Cao Yusheng, and continued to say to himself: "After Luca was born, two offspring were produced successively.

One of them is called archaea and the other is called eubacteria.

Fat Cao, guess which of these two is our ancestor?"

"That sounds weird. Cao Yusheng said helplessly, "The biggest problem with the theory of evolution is that it doesn't matter if the ancestor of human beings is a monkey, in the end, the ancestor simply became a bacteria, which makes people emotionally unbearable." ”

"Why do you look down on bacteria?" Miao Guangqi said, "Before your parents gave birth to you, half of your two parts were at your father's and half at your mother's, and the size was not much larger than bacteria. ”

"Whew. Cao Yusheng shook his hand, "Anyway, listen to the name, archaic, there is a 'ancient' word, that is the meaning of the old yellow calendar, can be ruled out, we should be the descendants of true bacteria, right?"

"That's right. Miao Guangqi said, "Then do you know the difference between archaea and eubacteria?"

"I know where to go. Cao Yusheng shook his head and said.

Miao Guangqi picked up the chopsticks and said to He Zihong: "The food is cold, I'll eat first, Lao He, you continue?"

"Good. He Zihong had already eaten almost all here, and took over the topic of Miao Guangqi, "The difference between archaea and eubacteria lies in the different molecular forms that use light energy.

After leaving the black chimney environment under the sea, there is still a lot of material in the entire ocean, which provides a material basis for ancient single-celled organisms to continue to evolve.

However, the gentle energy supply of the previous seabed is gone, which requires life to find and use new sources of energy, otherwise it will have to be trapped at the bottom of the sea forever.

The reason why archaea can surface is because they synthesize a class of molecular structures called 'retinaldehyde'.

This molecular structure can use the light energy of the sun to maintain the alkalinity in the cell, so as to maintain a certain acid-base difference between the inside and outside of the cell membrane, and then produce an acid-base neutralization reaction to provide energy for cellular activities.

Eubacteria, in a similar way, synthesize molecular structures called 'porphyrins', and can achieve similar results.

But of course there is a difference between the two, otherwise it would be a family.

Archaea are the first to surface compared to true bacteria.

In the spectrum of sunlight, green light has the most abundant energy, so the 'retinaldehyde' of archaea absorbs green light.

By the time the eubacteria surfaced, the earth was already full of archaeal mushrooms.

Under the heavy archaeal blanket, the eubacteria have to absorb the residual light energy except for the green light in order to get the energy of the sun.

If it doesn't absorb green light, it reflects green light.

So, we look at the descendants of eubacteria, and the plants in them are mostly green.

The green plants we see so far are not the work of nature, but the result of evolutionary competition. ”

When Cao Yusheng heard this, he sighed, thinking that he really couldn't chat with scholars, this was just a doctor's nonsense about buying a donkey, and he hurriedly asked: "Then what is the problem you are encountering now?"

"The problem we have is ......," Miao Guangqi said, "Fat man, what color is that nest?"

"Purple. ”

"What color are those stones in the territory of the Queen Mother of the West?"

"It's still purple. ”

"Then let me tell you, more than a billion years ago, archaea that synthesized light energy with 'retinaldehyde', they absorbed green light and reflected purple light, so they looked purple. Miao Guangqi knocked on the table, "We have reason to believe that the Queen Mother of the West, including those around it, is a descendant of archaea.

This is something that separated from us billions or even billions of years ago, and spread all over the world before we did.

Before the rise of eubacteria, they had an evolutionary first-mover advantage of hundreds of millions or even billions of years.

And the existence of the Queen Mother of the West has clearly told us that in this long evolutionary time, the descendants of archaea also gave birth to intelligent life.

And the scale of energy that this intelligent life can control is higher than that of the current human race.

Therefore, all the biological knowledge and experience that we have built on the evolutionary branch of eubacteria are used to study the descendants of archaea, which is the Yuanmuqiuyu.

To understand them, and even crack them, is bound to be a huge undertaking.

Lin Shuo's side wants results within a few days, which is impossible. ”

"Then what are you still dragging?" Cao Yusheng said, "Reply to Lin Shuo directly, and find another way." ”

"I'm different from you, I want face. Miao Guangqi rolled his eyes, "You are now the deputy leader of the decision-making team, coordinating the rear, you go and reply." ”

"Miao Guangqi, I look down on you!" Cao Yusheng scolded, and then took out the phone.

"Wait. Yang Tuo said at this time, "I seem to have a bit of an idea." ”

......
