The "Chemical Origin Theory" holds that life is native to the planet and evolved from inorganic substances. It divides the origin of life into four stages: first, the stage of generating small organic molecules from inorganic small molecules; second, the generation of biological macromolecules from organic small molecules; third, the formation of multi-molecules from biological macromolecules system; fourth, the organic multi-molecular system evolved into primitive life.

The most important point is that the genetic material that can replicate itself, for now, the only genetic material found on various planets is DNA and RNA. Perhaps human beings are too ignorant and have not experienced enough planets, or perhaps this is already a fact of the universe.

Some people find it inconceivable, why do substances with the same structure appear on different planets? To better explain this, there is a very famous mathematical game called "Game of Life".

The basic idea of ​​the "Game of Life" is to give an initial configuration, then formulate some basic rules, and observe whether there will be a series of similarities in the evolution of life.

At the beginning, all the cells were randomly distributed in a large grid, and the evolution rules were very simple, with only 4 short rules.

1. "Underpopulation": Any living cell that has less than 2 living neighbors will die.

2, "Normal": Any living cell will continue to live if there are 2 or 3 living neighbors.

3. "Overpopulation": Any live cell that has more than 3 live neighbors dies.

4. "Reproduction": Any dead cell will come alive if there are exactly 3 live neighbors.

Just such a few simple rules will evolve into extremely complex dynamic images, and these dynamic images will form very strange dynamic laws.

What does that mean?

In other words, through this game, it is explained that some very simple rules can evolve extremely complex structures, which actually have a lot in common with the birth and reproduction of life.

The craters and seabeds of each planet, these initial environments are almost the same. The high pressure and humid complex environment provide the same rules for the birth of life.

Under these rules, simple organic matter randomly assembles into complex organic matter.

These complex chemical substances can further synthesize DNA, RNA and other self-replicating genetic materials, thus explaining the universality of life in the universe. It also explains why the creatures that humans encounter all have genetic material.

Even though the types of these genetic materials are very different, they are still species centered on genetic material.

"Unfortunately, we haven't found the original DNA and RNA, that is, the simplest genetic material that can replicate itself... Otherwise, this hypothesis will really become a theorem."

This discussion was initiated by Professor Yamamoto of the Unreal Lab, and some geography experts who were on the Riley Star expedition.

Zhang Yuan sat below, just an ordinary audience.

He frowned, not knowing what Yamamoto was going to say, so he raised his hand and asked directly: "Professor Yamamoto, time is limited, I would like to ask what is the mass extinction of life you mentioned. Without approval, what scientific experiments are being done on Riley civilization? Especially biological virus experiments..."

"You have to know that although our current laws do not have any content on alien civilizations, this is a big loophole. However, random biochemical experiments are not allowed morally..."

"Your Excellency, Captain, I know, I know, I swear that I will not make mistakes in this regard." Yamamoto stood on the stage, a little impatient, probably because there are too many black histories, and people around looked suspiciously.

He quickly replied: "Listen to me first, it won't take up too much of your time."

"An example I just gave, the Game of Life..."

Various patterns about the "Game of Life" were displayed on the screen. "This game has a total of 256 rules. Under each rule, due to the difference in the initial conditions, the final result is also different."

"However, the laws it can form are still limited, namely: change ends in a constant image, periodic changes occur, image changes are almost random, and images have certain complex laws."

"If this two-dimensional game is compared to a civilization in a two-dimensional world, can it be understood in this way: change ends in a constant image, which is equivalent to a civilization with complete class solidification, and civilization will no longer change."

"Periodic changes have occurred, that is, the phenomenon of historical reincarnation has appeared. Although the image is dynamic, there is no progress. These two categories are all mediocre civilizations considered by the new civilization historiography."

"The image changes almost randomly, and there are certain complex laws in the image. These two situations have extraordinary possibilities. Our new history of civilization is precisely trying to penetrate this type of complex law..."

"Don't forget, there are only a few simple laws that support the operation of the game of life. And we usually believe that the laws that support the operation of the universe should also be simple. Can we get some inspiration from it?"

Zhang Yuan frowned and thought. Yes, this is just the simplest two-dimensional image. The real cosmic civilization is much more complicated than the two-dimensional image... But in some respects, can an individual civilization be compared to a three-dimensional image composed of certain laws? What about the geometry?

This is a very novel perspective, and many mathematicians have fallen into deep thought.

But it is too difficult to really decipher these mysteries.

Yamamoto changed the subject and continued: "By the way, everyone, the content of this meeting is not about the history of new civilizations, but about the impending spontaneous mass extinction of species on this planet."

Mass extinction?

A small number of people below have just heard about this topic and regained their senses.

He didn't keep it too close, he took out a finger-thick, wood-like thing from a box, and started an experiment on the spot.

"Look, this is the heart of the World Tree, which is the hardest part. This batch of heart comes from a 15-year-old small tree, which is as tough as a steel bar. Without the heart, the World Tree cannot grow It is so tall. Please rest assured that we have been specially sterilized, and you can observe it at a close distance."

Zhang Yuan took a short piece of tree heart handed over by the staff and broke it hard. It was so hard that even with all the strength in his body, he didn't even bend it at all.

"It is indeed a very good material."
