Chapter 617
Is there only the type of life that exists on Earth?
Obviously that's impossible, there's so much variety in the abyss alone.
However, Wang Yi’s foundation is human, so the route he seeks naturally starts from this!
Now the verification of the perfect sequence has begun, and he has also completed many changes in central nervous system cells.
But in order to solve the problem of the integration of one's soul and flesh.
Wang Yi also collected a large amount of various relevant data from Lin Shiqin.
Want to find the answer from it.
And through this search, he gradually realized that he must trace back to his own origins and find the original combination of life and magic.
Find the anchor points for tracing back one by one!
Are humans smart?
Humans, who have become the overlords of the earth, are of course smart.
Or it can be said that it is precisely because of intelligence that humans have become the overlords .
However, if humans are not stimulated by language and writing during the critical period of brain development after birth, and if they are not subsequently supplemented with knowledge, this kind of "intelligence" will be greatly restricted.
If we look at some of the lower-class black people, some natives in primitive tribes, and even children raised by wild beasts, and continue to regress, we can actually find that the lower limit of human ability is much lower than we imagined.
It seemed as if there was an invisible lock binding it.
The birth of life is a miracle of the Creator, just like a monkey typing on a typewriter, countless impossibilities formed the original source of life.
Following the path of his ancestors and looking back to the past, Wang Yi found various anchor points in the data, as if he had crossed the ancient and modern times and saw the weight of history...
How long have humans dominated the Earth?
This new overlord of the earth is so insignificant in the vast history of the earth.
Relying on living fossils such as archaea as an anchor point, and combining the analogy between Wang Yi's own DNA and the DNA of all mankind, he seems to be continuing this ancient record, tracing the legacy of his ancestors, and constantly moving forward.
Dinosaurs alone have three major periods: Triassic, Jurassic, and Cretaceous.
Stegosaurus and Tyrannosaurus Rex didn’t even live in the same period and never met each other…
When single-celled organisms gradually evolved into multi-celled organisms, having a "mouth" was good enough at first. As they became more and more complex and had more and more functions, they began to evolve a second "mouth".
This "differentiation" can be observed in biological embryos. There are two mouths in total. The first mouth during the embryonic period is used for eating insects and arthropods, called protostomes, and the first mouth is used for excretion by vertebrates, called deuterostomes.
Compared to the hundreds of thousands of years that humans have dominated the earth, the ancestors of humans were eaten as snacks by the ancestors of insects for hundreds of millions of years.
The first Anomalocaris to evolve eyes was Protostomidae, which ate its ancestors for 40 million years.
The second overlord, the trilobite, which evolved a full-body exoskeleton, was also a protostomite and ate its ancestors for 100 million years.
The third overlord of the ancestors of arthropods
Fortunately, the Protostomes were so strong that most of the competition took place among themselves, allowing the ancestors of mankind to survive and develop various escape talents.
One of the branches chose to continuously evolve the nervous system, enhance sensitivity, evolve the spine, strengthen neural control, and open up a new technology tree.
Therefore, after the mass extinction caused by the huge environmental changes from the Permian to the Triassic period reset all the advantages, human ancestors finally turned things around.
It was only after the mass extinction that the ancestors of mankind started to develop technology again, which allowed them to invent myelin, increasing the speed of nerve transmission from 2 meters per second to 100 meters per second, which gave them the future.
Dinosaurs, myelin, eyes, deuterostomes, multicellular, unicellular, archaea…
For a moment, Wang Yi seemed to be tracing history and found the epic embellishments left over from the Archaea period in his genes.
Meaningless fragments have no effect at all and will be removed by RNA trimming during transcription, but...
This is a record, a historical record...
But unfortunately, this is the limit of the information that can be traced at present.
Going further up, there seems to be information, but the source can no longer be found .
The final piece of the puzzle is missing to serve as an anchor.
"It's such a pity. We were just a little bit short..."
Wang Yi opened his eyes, and at this moment there was a dazzling golden light emanating from his eyes, like a god!
"Boss, this paper may be useful to you. It is a Nobel Prize from the 1980s. Although it is a bit old, it seems to be just right for your problem."
After Wang Yi had recovered, Lin Shiqin found another paper. This was a relatively old paper, from the 1980s.
But this paper made Wang Yi's eyes light up. Nobel Prize winner?
It turns out that I have been walking into a dead end, and it turns out that there has always been an answer!
In the eyes of this Nobel Prize winner, the process in which the DNA in the cell nucleus transmits information to RNA, and then RNA uses organelles to manufacture various proteins is somewhat "redundant".
I always feel that the addition of an RNA link is a bit weird.
So some related experiments were conducted.
A series of experiments were conducted using a single-celled organism called Tetrahymena.
Tetrahymena has a useless DNA sequence that is quickly cut out by itself after being transcribed into RNA, and then pieced together again.
According to the experimenters' understanding, there should be a protein that can recognize this useless sequence and then complete the cutting and stitching work.
He then began his own experiment, putting together all the proteins extracted from Tetrahymena and a segment of RNA molecule that had not been cut, continuously eliminating the proteins that did not participate in the cutting process, leaving only those that naturally had the cutting function.
Just keep using the "process of elimination" to force your way through.
The experiment went quite smoothly and the amount of protein was continuously reduced.
However, he later discovered that even after removing all the proteins, RNA could still be cut.
In other words, RNA has both the ability of DNA to store information and the ability of protein catalysis.
If, by some accident, a biologically active substance were to be created, but it could not replicate itself in a harsh environment, it would be meaningless and would soon disappear.
Therefore, self-replication is recognized as the origin of life.
DNA is the manual of life, RNA transcribes it, and proteins cooperate to participate in various reactions to make it come true.
Proteins themselves require DNA, the manual of life, which creates the paradox of which came first, the chicken or the egg.
But if RNA molecules can connect short chains of amino acids together, then it seems that all problems will be solved.
At present, this hypothesis has not been verified.
This is also the reason why it was ignored at first.
But Wang Yi doesn't need evidence.
If there is no way to verify it, then verify it yourself.
The original anchor point, the origin of the Tree of Life, the ancestor of all spirits...
