At noon on this day, Canteen No. 1 in Kunlun Park.
According to the park's plan, there must be five canteens in the entire Kunlun Park, but so far there are not many staff members in the park, and only the No. 1 canteen has been opened.
The master chef of No. 1 canteen is Zhou Lingshi, and his wife Wang Jinhua helps him.
With Zhou Lingshi in charge, the food level is naturally very good. Director-level figures like Cao Yusheng and Yang Tuo, in addition to the normal work set menu, Zhou Lingshi will add two dishes for them, and Wang Jinhua will bring them to the box.
The location of this box is relatively remote, and the sound insulation is good. Cao Yusheng and Yang Tuo are used to eating here, and they can communicate with each other at noon, and share the frontline and progress.
There are more people at this table at noon today, including Miao Guangqi and He Zihong.
In this way, four of the seven-member decision-making team of the Kunlun Project were present.
Among the four, Cao Yusheng, as one of the deputy team leaders, was responsible for coordinating the rear work.
The old mastermind naturally knew about the lair, and was also waiting for the results of the research institute's research.
Looking at the state of the three of them now, he had a vague idea.
Two old and one young, their faces are a little blue, their eyes are bloodshot, it looks like they stayed up all night last night.
And there is no joy on his face, which shows that the progress is slow and there is no result for the time being.
So Cao Yusheng felt a little strange, and said to Miao Guangqi, "Is there anything in this world that can bother you?"
Miao Guangqi rolled his eyes: "Nonsense, if nothing in this world can stop me, Lin Shuo should be my son by now."
"You're wrong." Cao Yusheng smiled slightly, "Maybe my wife is good for others, but my son must be good for me. Miao Chengyun is not bad."
"Okay, I'm not in the mood to joke with you now." Miao Guangqi looked a little impatient, and then said to Yang Tuo, "Xiao Yang, do you have any thoughts?"
Yang Tuo covered his head and turned a deaf ear to Miao Guangqi's question.
Miao Guangqi looked a little deflated, and then glanced at He Zihong.
He Zihong hurriedly said: "This child is like this when he is focused. He doesn't care much about others. It will be fine when there is a result."
"It looks like we have to wait for a while." Miao Guangqi shook his head.
"It's not Lao Miao, what you mean..." Cao Yusheng frowned, "I don't have any clue?"
"I can't tell you, a layman." Miao Guangqi said with a look of disgust, "Scientific research, first of all, is to discover the objective laws of things.
It is absolutely rational and requires absolute objectivity.
It’s not that we just go here to get what we want.
Instead, we find something in it, and then figure out how to apply it.
Of course, it is not pure luck, there will be assumptions in advance.
This hypothesis is often a self-consistent mathematical model, or observation data over the years, which exists as a theoretical guide for experiments.
However, during the experiment, these theories may be overturned, which requires scientists to find new laws and verify them through experiments... "
"Whispering." Cao Yusheng waved his hand impatiently, "Speaking of people, where are you stuck?"
"Isn't it just that the previous theory has been overthrown, and the new law has not been found yet?" Miao Guangqi spread his hands.
"No, your biological research is not physical research. Where did you get the mathematical model?" Cao Yusheng said, "Isn't it all a hypothesis? It's not normal for a hypothesis to be overthrown. Why don't you come up with 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, "The current establishment of our human biology is based on the research findings on our biological evolutionary branch. Our evolutionary branch, going back several billion years, the ancestor is called 'Luka', have you heard of it?"
Cao Yusheng shook his head, then said, "I know 'Lucy'."
"Lucy is an ancient human in East Africa, the ancestor of human beings." Miao Guangqi said, "I said 'Luka', which is a kind of rock cell."
"Rock cells?"
"Yes, there are many hypotheses about the origin of life, but in my opinion, the most reasonable one is the black chimney on the seabed." Miao Guangqi said, "Near the Galapagos Islands in the central Pacific Ocean, there is a crack on the seabed. There are such black chimneys at the bottom of the rift valley.
The so-called black chimneys are actually craters on the ocean floor.
The billowing black smoke from the black chimney is the scene formed by the sulfide inside the volcano being squeezed into the high-pressure seawater.
Unlike above-ground ecosystems powered by sunlight, this one is powered purely by geothermal heat.
Those sulfides are the nutrients for the surrounding life.
The material erupted from the submarine volcano was cooled by the high-pressure seawater, and instantly solidified into a loose material, which was full of small cavities with a diameter of less than 100 microns.
This pore size is roughly equivalent to a cell.
Based on the above observation results, there is a hypothesis of the biological origin of the seabed black chimney.
More than four billion years ago, the earth was still a vast ocean, and there were countless such black chimneys on the seabed.
Some volcanic eruptions are strongly alkaline, and seawater is often acidic.
Between the acid and alkali, there is a layer of rock that can slowly infiltrate materials, which allows the energy brought by the acid-base neutralization reaction to be released in an orderly manner.
This kind of delicate chemical energy catalyzes the organic matter in the small cavities of the chimney stone walls.
Afterwards, in the environment of hundreds of millions of rock cells in the long years, RNA and DNA were synthesized successively, began to replicate and spread by itself, 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' relies, is this delicate acid-base neutralization reaction.
This is the configuration at the bottom of our evolutionary branch, and it was already decided when our ancestors were still rock cells.
It is also the upper limit of the energy that we humans can use, the chemical energy brought by the acid-base neutralization reaction, the so-called end of human cultivation power, this is the ultimate shackle. "
"Hey, this is the first time I heard about it." Cao Yusheng shook his head, "Then what? What is the problem you are facing now?"
Miao Guangqi ignored Cao Yusheng, and continued on his own: "After the birth of Luca, two descendants were born.
One of them is called an archaea and the other a eubacteria.
Fatty Cao, guess which of these two is our ancestor? "
"This 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 was a monkey, but in the end the ancestors simply turned into bacteria. Can't take it."
"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 the other half were at your mother's. The size is not much larger than bacteria."
"Hey." Cao Yusheng shook his hands, "Anyway, listen to the name, archaea, there is a word 'ancient', which means the old almanac, we can rule it out, we should be the descendants of eubacteria, right?"
"That's right." Miao Guangqi said, "Then do you know the difference between archaea and eubacteria?"
"I don't 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 getting cold, I'll eat first, Lao He, can you continue?"
"Okay." He Zihong had almost finished his meal here, and took up 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 on the seabed, there is still a lot of material in the entire ocean, which provides the material basis for the continuous evolution of ancient single-celled organisms.
However, the mild energy supply at the bottom of the sea before is gone, which requires life to find and use new energy sources, otherwise it can only be trapped on the bottom of the sea forever.
The reason why archaea can float to the surface is because it synthesizes a class of molecular structures called 'retinaldehyde'.
This molecular structure can use the light energy of the sun to maintain the partial alkalinity in the cell, so as to maintain a certain acid-base difference between the inside and outside of the cell membrane, and then generate an acid-base neutralization reaction to provide energy for cell activities.
Eubacteria, too, are similar in that they synthesize molecular structures called 'porphyrins' that can achieve similar effects.
But of course there is a difference between the two, otherwise they would be a family.
Archaea floated to the surface of the sea one step earlier than eubacteria.
In the spectrum of sunlight, green light has the most energy, so the 'retinaldehyde' of archaea absorbs green light.
By the time the eubacteria floated to the surface, the earth was already full of archaeal creep.
Under the thick carpet of archaea, eubacteria have to absorb the residual light energy except green light in order to obtain the energy of sunlight.
If it does not absorb green light, it reflects green light.
So, when we look at the descendants of eubacteria, most of the plants are green.
The green plants we see now are not the uncanny workmanship of nature, but the result of evolutionary competition. "
Cao Yusheng sucked his teeth when he heard this, thinking that he really can’t chat with scholars, this is simply nonsense about a doctor buying a donkey, so he hurriedly asked: "Then what is the problem you are encountering now?"
"The problem we encountered was..." Miao Guangqi said, "Fatty, look at that lair, what color is it?"
"It's purple."
"What color are the stones in Queen Mother Xi's site?"
"It's still purple."
"Then let me tell you, more than a billion years ago, the archaea that used 'retinaldehyde' to synthesize light energy absorbed green light and reflected purple light, so they looked purple." Miao Guangqi knocked on the table, " We have reason to believe that 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 us.
Before the rise of eubacteria, they had an evolutionary first-mover advantage of hundreds of millions or even billions of years.
The existence of the Queen Mother of the West has clearly told us that during this long evolutionary period, the descendants of archaea also gave birth to intelligent life.
And the energy scale that this kind of intelligent life can control is higher than the current human beings.
Therefore, all the biological knowledge and experience we have built on the eubacterial clade to study the descendants of the archaea, that is, to seek fish from trees.
It must be a huge project to understand them, or even crack them.
It is impossible for Lin Shuo to get results within a few days. "
"Then why are you procrastinating?" 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 head of the decision-making team, and you will take care of the rear and reply."
"Miao Guangqi, I look down on you!" Cao Yusheng cursed, then took out his phone.
"Wait a minute." Yang Tuo said at this time, "I seem to have a little idea."
