Chapter 722: The Origin of Life

At noon that day, Canteen No. 1, 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 this No. 1 canteen has been opened.

The master of the No. 1 cafeteria was Zhou Lingshi, and his wife Wang Jinhua helped him.

With Zhou Lingshi's hands on the food, the food level is naturally very good. In addition to the normal work package, Zhou Lingshi will also add two dishes to them for Wang Jinhua to bring them to the private room.

The room is relatively remote and has good sound insulation. Cao Yusheng and Yang Tuo are used to eating here. They can communicate with each other at noon. Let's share the front line and progress.

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

In this way, four of them were present in the seven-member decision-making team of Kunlun Plan.

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

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

At this moment, he saw the status of the three of them, and he knew it vaguely.

The two old ones and one young ones had a little blue face and bloodshot eyes. It seemed that they had been staying up all night last night.

And the lack of joy on his face means that the progress is slow and there will be no results for the time being.

So Cao Yusheng was a little surprised and said to Miao Guangqi, "There is still something in this world that can stump you?"

Miao Guangqi rolled his eyes and said, "Nonsense, if nothing in this world could be difficult for me, Lin Shuo should be my son now."

"That's wrong with you." Cao Yusheng smiled slightly, "Maybe my wife is good for others, but my son must be my own. Miao Chengyun is not bad."

"Okay, I'm not in the mood to joke with you now." Miao Guangqi's face was a little impatient, and then said to Yang Tuo, "Xiao Yang, do you have any ideas?"

Yang Tuo covered his head and turned a deaf ear to Miao Guangqi's question.

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

He Zihong quickly said, "This child is like this when he is focused, he doesn't care much about others. It's good to wait until there is a result."

"It seems, I have to wait for a while." Miao Guangqi shook his head.

"It's not Lao Miao, I heard what you mean..." Cao Yusheng frowned, "Is he not at all clue?"

"You can't tell me, an outsider." Miao Guangqi said with a disgust, "Scientific research work first is to discover the objective laws of things.

It is absolutely rational and requires absolute objectivity.

It doesn’t mean that we just go to get whatever we want.

But on the other hand, we find something in it and then think about how to apply it.

Of course, it is not just a big fortune, there will be assumptions in advance.

This assumption is often 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 rules and verify them through experiments..."

"It's so silly." Cao Yusheng waved his hand impatiently, "Where are you stuck in the human language at the moment?"

"Isn't this stuck with the overturn of the past theory? The new rules have not been found yet?" Miao Guangqi spread his hands.

"No, your biological research is not physical research, where do you come from mathematical models?" Cao Yusheng said, "Isn't it all hypothesis? It's not normal for hypothesis to be overturned. You should propose another 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 research and discovery on our biological evolutionary branch. Our evolutionary branch has been poured up for billions of years. The ancestor was called "Luka". Have you heard of it?"

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

"Lucy is the ancient human being in East Africa and the ancestor of human beings." Miao Guangqi said, "I mean 'Luca', this 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 under the sea." Miao Guangqi said, "Near the Galapagos Islands in the middle of the Pacific, there is a rift on the bottom of the sea, and there is such a black chimney at the bottom of the rift.

The so-called black chimney is actually a crater on the bottom of the sea.

The rolling black smoke rising above the black chimney is the scene where sulfides inside the volcano are squeezed into high-pressure seawater.

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

Those sulfides are the nutrients of the surrounding life.

The substance erupted from the undersea volcano is cooled by high-pressure sea water and instantly solidifies into a loose substance, which is covered with small cavity less than one hundred microns in diameter.

The size of this pore is roughly equivalent to one cell.

Based on the above observations, there is the hypothesis of biological origin of black chimneys under the sea.

More than four billion years ago, the earth was still a vast ocean, and there were countless such black chimneys under the sea.

Some volcanic eruptions are strongly alkaline and seawater is often acidic.

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

This delicate chemical energy gave birth to organic matter in the small cavity of the chimney stone walls.

Then, over the long years and in the environment of hundreds of millions of rock cell, RNA and DNA were synthesized one after another, began to replicate and spread, and our ancestor "Luka" was born.

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

This is the lowest configuration of our evolutionary branch, and it was decided when our ancestors were still rock cells.

It is also the upper limit of our human energy that uses, the chemical energy brought by the neutralization reaction of acid and alkali. The so-called end of human cultivation is the ultimate shackle.”

"Wow, the first time I heard it." Cao Yusheng shook his head, "Then what? What's the problem you are facing now?"

Miao Guangqi ignored Cao Yusheng and continued to say "After Luka was born, two descendants were produced one after another.

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

Fatty Cao, guess which of these two is our ancestors?"

"This sounds very disgusting." Cao Yusheng said helplessly, "The biggest problem with evolution theory is that it is fine if the ancestors of humans are monkeys. In the end, the ancestors simply turned into bacteria, which makes people unable to bear it emotionally."

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

"Yeah." Cao Yusheng shook his hand, "Anyway, the name is the archaeological beast. It has the word "ancient" which means the old almanac. It can be ruled out. We should be the descendants of real bacteria, right?"

"That's right." Miao Guangqi said, "Then do you know what the difference between archaeological and eobacteria?"

"Where do I know how 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 have a meal first. Lao He, please continue?"

"Okay." He Zihong had almost eaten here and took over Miao Guangqi's topic. "The difference between archaea and eobacteria is that the molecular forms that use light energy are different.

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 the continued evolution of ancient single-cell organisms.

However, the mild energy supply under the sea before was gone, which requires life to find and utilize new sources of energy, otherwise it will only be trapped at the seabed forever.

The reason why archaea can float on the surface is because it synthesizes a molecular structure called 'retinaldehyde'.

This molecular structure can use the sun's light energy to maintain the alkalinity in the cells, thereby maintaining certain acid-base differences inside and outside the cell membrane, thereby producing acid-base neutralization reactions and providing energy for cell activities.

Euobacteria are similar. They synthesize molecular structures called 'porphyrin' and can achieve similar effects.

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

Compared with eubacteria, archaea floats on the surface of Shanghai first.

In the sunlight spectrum, green light is the most abundant energy, so the archaea's "retinaldehyde" absorbs green light.

By the time the eugenic bacteria floated on the surface of the Shanghai area, there were already blankets of archaea everywhere on the earth.

Under the thick archaeological blanket, in order to obtain the energy of sunlight, eobacteria have to absorb the residual light energy besides green light.

If you do not absorb green light, you will reflect green light.

So, let’s look at the offspring of eugenic bacteria, most of which are green.

The green plants we see at present are not the magical arts of nature, but the result of evolutionary competition."

When Cao Yusheng heard this, he sucked a tits and thought that he really couldn't chat with scholars. This was simply a lot of nonsense about buying donkeys by doctors. He quickly asked, "What is the problem you are facing now?"

"The problem we encountered was..." Miao Guangqi said, "Fatty, what color is that nest?"

“It’s purple.”

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

"It's still purple."

"Then I tell you that more than a billion years ago, archaea that used 'retinaldehyde' to synthesize light energy. They absorbed green light and reflected purple light, so they looked purple." Miao Guangqi knocked on the table, "We have reason to think that Queen Mother of the West, including those around it, is descended from the archaea.

This is something that was separated from us more than a billion or even billions of years ago, and it spread all over the world earlier than us.

Before the rise of eobacteria, they had the first-mover advantage in evolution for hundreds of millions or even billions of years.

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

And the energy scale that this intelligent life can control is above the current human beings.

Therefore, all the biological knowledge and experience we have built on the evolutionary branch of eubacteria to study the descendants of archaea, that is, seeking fish from the tree.

To understand them or even crack them, this must be a huge project.

It is impossible for Lin Shuo to have a result within a few days."

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

"I'm different from you, I want shame." Miao Guangqi rolled his eyes, "You are now the deputy leader of the decision-making group, and you can reply."

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

"Wait first." Yang Tuo said at this time, "I seem to have some idea."
