On the contrary, he had very few dreams, and even if he did dream, he would hardly remember the dream after waking up.
But this time the situation is obviously special.
He remembered this dream clearly and it was very impressive.
At first, Zhou You felt that his body was floating lightly.
He didn't know where this was, he could only see an empty world of yellow, orange and orange.
He can also feel the wind.
Although his own existence seems very strange, as if he is in a staggered parallel space and is not affected by the outside world, he can still feel the existence of the wind.
In the dream world, Zhou You seems to have lost his accurate perception of time.
Even though his own mind was very clear that this was indeed a dream, he just felt as if he had stayed in this void space for an extremely long time.
It could be decades, it could be hundreds of years, it could even be tens of thousands or even hundreds of millions of years.
This space was so boring and dull that for a while he felt like he was about to collapse.
But the strange thing is that his mind seems to be locked.
No matter how painful he is in his heart, his mental state is always forcibly locked in wakefulness, and he cannot even break down to escape the pain.
Finally, Zhou You saw some new changes.
A sparkling object appeared in his field of vision.
That thing was far away from him.
For the first time, Zhou You felt the urge to get closer and take a closer look at the things in this dream world.
Something wonderful happened.
When he had this impulse in his heart, he could clearly feel that the light spot was getting bigger and bigger, and he was getting closer to the other party.
Perhaps just a moment passed, and he appeared directly in front of the light spot.
But the angle of view continued to widen, until after it was completely close, Zhou You found that he saw a "molecular formula".
He didn't know what kind of vision he had, let alone why human eyes could see this thing.
But when he looked at the ball in front of him and the lines of light traces that seemed to be traces of something passing through at high speed, he just felt that this was a molecular formula.
The spheres one after another are the atoms that make up the molecule.
Those traces of light are chemical bonds.
The chemical formula in front of Zhou You is very complex, not like a simple inorganic substance, but like an organic macromolecule.
Zhou You looked at the chemical formula and felt both strange and familiar at first, but after a while he recalled a paper he had read a few months ago when he was at work.
This paper puts forward a conjecture and elaborates on the author's explanation and speculation on the origin of life on earth.
Many people believe that life on earth was not a complete life form in its earliest days, but a self-replicating organic molecule generated by a coincidence with an infinitely low probability of birth, almost as low as non-existent.
The environment in which this organic molecule is located happens to be the most appropriate temperature, and there are other most appropriate molecules around it that can meet the conditions for its self-replication reaction.
As long as the above conditions are met, this large molecule can be regarded as real life to a certain extent.
The name of this organic molecule is diamide phosphate.
This theory seems quite tenable.
But there are also many people who oppose this speculation.
Because according to scientists' probabilistic calculations, the possibility of meeting such complex preconditions, generating a molecule with a complex structure at once, and having the surrounding environment just right is so low that it is almost equal to zero.
Even if the time span is extended to billions of years and the space scope is expanded to include the trillions of planets in the entire galaxy, the probability is still basically zero.
Of course, both opponents and supporters of the molecular theory of the origin of life basically agree that the first organic molecule ultimately set the tone for the entire history of life on earth.
The difference lies in how this molecule is generated.
In addition to the molecular theory, there is another inference that is equally well known and is regarded as Guigao by countless people.
That is the theory of cultivating extraterrestrial life.
Combining the existing known knowledge on the earth, numerous paleontological research results, and the tone of the theory of cultivating extraterrestrial civilizations, many people believe that the first life on earth was directly prokaryotic anaerobic bacteria, but
Prokaryotic anaerobes introduced by advanced alien civilizations.
This argument skips over the emergence and evolution of macromolecules, but is a complete microbial life form from the beginning.
In this conjecture, the original chance was completely eliminated, and chance was directly transformed into an inevitable choice for alien release.
From a probability perspective, the theory of cultivating extraterrestrial civilizations is actually more scientific, more reasonable, and more likely.
But this argument is somewhat hurtful to human feelings, so that even though most people know that it is more reasonable, they are unwilling to face it.
Now, the molecular formula that Zhou You saw was highly similar to the diamide phosphate mentioned in the paper he saw.
Traveling around in a dream feels like it’s magical.
People used to say that there is a clear connection between people's dreams and reality, but in Zhou You's opinion, this connection is a bit too bizarre.
Zhou You did not think that the article, which lacked actual evidence and was more likely to be conjecture than scientific conclusion, was correct.
But the strange thing is that a few months later, the scene described in this paper appeared in my dream again.
Next, Zhou You "saw" that the molecule suspected to be diamide phosphate actually started a chemical reaction with the surrounding small molecules.
Perhaps the shortest RNA chain composed of four phosphorylated nucleosides in the history of the earth appeared.
The diamide phosphate then encounters glycerol and fatty acids in the same area.
"It just so happens" that there is another relatively simple organic molecule generated by accident - imidazole, which can become a catalyst.
Immediately afterwards, under the catalysis of imidazole, diamide phosphate produced a large piece of phospholipid material after a long series of wonderful reactions.
What's even more coincidental is that after the phospholipid was generated, due to its own chemical bonding characteristics, it began to be linked with less stable secondary chemical bonds in the water, forming a "bubble" structure in the water.
This bubble just happens to trap the diamide phosphate and the previously generated RNA chain inside.
What's more coincidental is that there are four other nucleosides in this bubble, as well as some basic amino acids such as glycine, aspartic acid and glutamic acid.
Diamide phosphate is still busy.
According to the reaction process driven by the most basic chemical reaction principles, it phosphorylates glycine, aspartic acid and glutamic acid, and generates a short peptide chain.
The diamide phosphate then grabs four more nucleosides, creating a second RNA strand with four nucleosides.
But this time, the order of formation of the RNA chain is exactly opposite to that of the first time. Last time, the reaction started from point A to point B, but this time it reacted all the way from point B to point A.
This results in the RNA generated twice being like two magnets, each with four "magnet north and south poles" that are completely staggered.
Subsequently, the two RNA strands met in the water and were spliced together due to the magnetic attraction of the positive and negative electrodes to form a DNA strand.
Including the outer shell of short peptide chains and phospholipids, this is a complete biological structure.
The first real living thing on earth was born.
While drifting slowly, the diamide phosphate bumped into the DNA chain again.
This time, the diamide phosphate squeezes into the different magnetic poles between the two RNA strands, forcing them apart.
But the two RNA strands were not separated forever. Instead, they used the time they were apart to quickly capture the previously generated peptide chains floating around, and then assemble them in order.
The basis of all life, protein was born.
One of the special protein structures formed by chance can capture organic molecules in water and synthesize new diamide phosphate macromolecules.
The diamide phosphate generated this time is the self-replica of the original light spot, and has officially entered the category of biological enzymes.
Since then, the first living thing on earth has survived.
Perhaps before Zhou You saw this reaction, similar reaction processes had occurred countless times in countless puddles, puddles and seawater on the vast earth.
But every time, due to lack of material, inappropriate temperature, too fast water flow, or too much liquid, the wonderful encounter failed to happen, and the success failed again and again.
But in the end, after countless failed attempts over the years, I finally succeeded this time.
After that, Zhou You watched as the first generated cells frantically consumed the basic organic matter that had been generated in the surrounding water flow during hundreds of millions or even billions of years of lightning reactions, and continued to replicate itself crazily.
These primitive biological cells flowed in all directions along the water flow, slowly spreading, consuming the earth's materials faster.
This is the Precambrian period, and it is also the history of the origin of life on earth.
The first page of the history of life on earth begins with a molecule stubbornly replicating itself.
That is a "human" epic.
The flow of time began to accelerate, and more than three billion years passed in an instant.
About 600 million years ago, mutations occurred.
Due to the consumption of earth's resources by microbial systems for more than three billion years, a huge amount of carbon dioxide has accumulated in the earth's atmosphere.
At this time, cyanobacteria with photosynthetic capabilities that can consume carbon dioxide and generate oxygen appear.
The emergence of large amounts of oxygen paved the way for Earth's organisms to move from single-cell organisms to more complex multi-cell biological structures.
After that, life on earth began to explode.
Right under Zhou You's eyes, creatures began to iterate and evolve rapidly.
This is the Cambrian period.
The Cambrian Period lasted tens of millions of years.
During this period, trilobites appeared.
The concept of male and female emerged.
Creatures began to have heads, legs and other organs.
Creatures have even evolved photoreceptors, the most primitive eyes.
Life on Earth has seen the light.
The traveling eyes also followed important mutations time and time again in the history of Earth's biology, personally witnessing the germination, development, and then complete birth or destruction of each new species.
Zhou You didn't know if he had become an omniscient and omnipotent god in his dream, but he could see with his eyes and record every change that occurred at the genetic level.
His mind was not bombarded by this massive amount of information, he just instinctively acted as an observer and recorder.
Immediately afterwards, the history of life on earth entered the Ordovician period.
The Ordovician biological radiation occurred.
Many biological phyla and classes born in the Cambrian began to take different paths due to different environments and different needs, forming different families.
Then, there was the first mass extinction of species that cut off the Ordovician and Silurian periods with a single blow.
During the mass extinction, about 60 percent of the species on Earth were buried in the dust of history.
Human scientists in the past had three main conjectures about the causes of the first mass extinction.
One theory is that it is cyclical changes in climate, another is that an asteroid hit the earth, and the third theory is that the gamma rays released when a supernova exploded happened to cover the solar system and the earth, seriously damaging the earth's ozone layer.
, and at the same time completely destroyed the atmospheric environment on Mars, extinguishing the possibility of life on Mars.
Previous anthropologists have debated endlessly around these three hypotheses.
Zhou You himself is not a fan of any of these theories.
His own knowledge is not biased. He believes in all three major theories, but also believes in none.
But now, in his own dream, Zhou You completely abandoned the other two hypotheses.
He "with his own eyes" saw the earth's sky suddenly light up, and then "with his own eyes" he "watched" with his own eyes the gamma particle stream rushing down from the sky and scattering on the earth and oceans.
He also watched "with his own eyes" as the undersea ecology, which was as prosperous as an ancient city, rapidly withered.
However, life on earth was not completely destroyed. After all, 40% of life successfully withstood the disaster and entered the Silurian Period with the mission of reproduction or the instinct of biochemical reactions.
In the Silurian Period, ferns in the sea began to step onto the ground and became terrestrial plants.
Vertebrates with greater athletic ability became the new overlords of the sea.
Fish dominate the oceans.
It seems that if nothing unexpected happens, fish will slowly evolve higher intelligence and become a true civilization.
Time slowly moved from the Silurian Period to the Devonian Period.
But just like the first mass extinction, accidents happened again.
At the end of the Devonian period, several huge celestial bodies fell from the sky and hit the earth hard.
The earth shook, the crust was pierced, and magma erupted.
Toxic gases rose from holes in the earth's crust, covering the earth with gray smoke.
Smoke and dust have covered the sky for millions of years. This has made it difficult for photosynthetic plants in the ocean to survive and have died out.
The accumulation of various factors has made the ocean extremely hypoxic.
A large number of creatures living in the sea began to become extinct one after another, especially fish.
The Devonian Period ended.
More than 75% of life on earth also stops here.
But disasters and opportunities will always coexist.
Although the disaster at the end of the Devonian period was tragic, it left a rich legacy for the next generation.
There is insufficient oxygen in the ocean, but the oxygen in the air has reached a very high concentration after hundreds of millions of years of efforts by photosynthetic plants.
The massive volcanic ash released by the violent volcanic eruptions caused by the impact of celestial bodies, as well as the disintegrated celestial bodies themselves, brought rich nitrogen and phosphorus elements to the earth.
These are the sources of life.
In the tragic ruins, amphibians trapped in diving evolved lungs through painful iterations, allowing them to breathe air directly. Animals on the earth officially set foot on the earth.
The Carboniferous Period begins.
Arthropods and reptiles began to take the stage and became dominant.
