Chapter 618: Weak(2/3)

On top of that are chimpanzees, which share 99% of their genes with humans. They belong to the same species as humans, and both share a common ancestor about 7 million years ago.

Above that is the subfamily Hominidae, which is composed of humans and gorillas, and then there is the subfamily Hominidae, which is composed of the orangutan subfamily, and then there are the primates.

With continuous division, all life on earth can eventually be classified into this tree of life!

Although at present, this work still has a long way to go.

The DNA of humans and flies is about 40% identical. The difficulty of classification is naturally here. The diversity of many organisms can only be improved and speculated through archaeology and fossils.

But after the division of the three major domains of bacteria, archaea, and eukaryotes is completed, we finally have the backbone, and the rest is to complete the puzzle.

But now, more and more information collected by Wang Yi shows that the original three main branches may have just turned into two domains.

Bacteria and Archaea!

Needless to say, bacteria are very clear to many people. They have a relatively simple structure and do not have too complex cell structures.

Archaea may sound unfamiliar to many people. It is a type of organism that is usually found in extreme environments such as volcanic craters and hot springs.

Because the living environment is too extreme, the number of samples taken so far is not large. Many samples show that archaea are usually relatively simple, just because they adapt to different environments and have obvious molecular structure differences with bacteria.

But this kind of sampling is relatively simple for Umbrella.

The material strength b is stacked up, and there is almost no place that cannot be sampled by unmanned operation.

Therefore, Umbrella collected many unique archaea, which have complex cell structures like eukaryotes.

It seems to be confirmed that the origin of eukaryotes may have evolved from these complex archaea...

Chapter 617

Is life only of the earth type?

Obviously impossible, there are many kinds of things in the abyss alone.

However, Wang Yi's own foundation is human beings, so the route he seeks naturally starts from this!

Now that the verification of the perfect sequence has begun, he has also completed many changes in central nervous cells.

But in order to solve the problem of the union of spirit and body.

Wang Yi also collected a large amount of various related data from Lin Shiqin.

Want to find the answer from it.

And this search gradually made him understand that he must trace his own origin and find the original combination of biology and magic.

Find the anchor points that lead back to each other!

Are humans smart?

Human beings who have become the overlords of the earth are certainly smart.

In other words, it is precisely because of intelligence that humans have become the overlords of the earth.

However, if human beings are not stimulated by language and writing during the critical period of brain development after birth, and are not filled in with knowledge subsequently, this kind of "smartness" will also be greatly restricted.

If you look back at the beautiful little black men at the bottom, the indigenous people in primitive tribes, and even the children raised by wild animals, you can actually find that the lower limit of human ability is much lower than imagined.

There seems to be an invisible lock binding it.

The birth of life is a miracle of the Creator, just like a monkey tapping a typewriter, the original source of life was formed from countless impossibility.

Following the path of his ancestors and looking back on the past, Wang Yi found various anchor points in the many data, as if he were crossing the ancient and modern times and saw the weight of history...

How long will it take for humans to dominate the earth?

This new overlord of the earth is so insignificant in the vast history of the earth.

Relying on the living fossils of archaea as an anchor, and combining the analogy between Wang Yi's own DNA and the DNA of all humans, he seems to be continuing this ancient record, pursuing the legacy of his ancestors, and constantly moving forward.

Dinosaurs alone have three periods: the Triassic, the Jurassic, and the Cretaceous.

This chapter is not over yet, please click on the next page to continue reading! Stegosaurus and Tyrannosaurus rex did not even live in the same period and have never met...

When single-cell organisms gradually evolved towards multi-cells, it was good to have one 'mouth' at first. As it became more complex and had more and more functions, a second 'mouth' began to evolve.

This 'distinction' can be observed from the biological embryo. There are two mouths in total. In the embryonic period, the first mouth is used for eating, which is insects and arthropods, called protostomes. The first mouth is used for excretion, which is vertebrates.

It's called a deuterostome.

Compared to the hundreds of thousands of years when humans have dominated the earth, our ancestors were eaten as snacks by our insect ancestors for hundreds of millions of years.

First, the first anomalocaris to evolve eyes was Haraguchi, which ate its ancestors for 40 million years.

The second overlord trilobite that later evolved an exoskeleton was also Haraguchi, and had eaten its ancestors for 100 million years.

The third overlord of the arthropod ancestors, the sea scorpion, was also a protostomia. The fourth cornerstone that evolved a beak capable of breaking armor was still a protostomia. The first step in evolution directly accumulated hundreds of millions of years of long-term advantages for the protostomes.

Fortunately, the original mouth creatures are so powerful that most of the competition is conducted internally, allowing the ancestors of mankind to survive and activate various escape talents.

One of the branches chose to continuously evolve the nervous system, strengthen sensitivity, evolve vertebrae, strengthen neural control, and open a new technology tree.

Therefore, after the mass extinction caused by huge environmental changes from the Permian to the Triassic, all advantages were reset, and human ancestors finally turned around.

That is to say, after the mass extinction, we started to use technology again, which allowed the ancestors of mankind to activate myelin sheaths, and the nerve transmission speed increased from 2 meters per second to 100 meters per second. Only then can we have a subsequent future.

Dinosaurs, myelin, eyes, deuterostome, multicellular, unicellular, archaea...

For a moment, Wang Yi seemed to be tracing history and finding epic embellishments in his genes that belonged to the archaeal period.

Meaningless fragments have no effect at all and will be trimmed out by RNA during transcription, but...

This is a record, a historical record...

But unfortunately, the information that can be traced so far ends here.

Further up, there seems to be information, but the source cannot be found because there is no reference.

The last piece of the puzzle is still missing to serve as an anchor.

"It's really a pity. It's obviously only a little bit short..."

Wang Yi opened his eyes, and at this time, his eyes were exuding a dazzling golden light, like a god!

"Boss, this paper may be useful to you. It is from the Nobel Prize in the 1980s. Although it is a bit old, it seems that it should be able to answer your question."

After Wang Yi recovered, Lin Shiqin found another paper. This was an older paper, dating from the 1980s.

But this paper made Wang Yi's eyes light up, the Nobel Prize winner?

It turns out that I have hit a dead end all along, and it turns out that I have an answer all along!

In the eyes of this Nobel Prize winner, the DNA in the cell nucleus transmits information to RNA, which then uses the organelles to manufacture various proteins. The process itself is somewhat 'redundant'.

I always find it a bit strange to have an extra RNA link.

So some related experiments were conducted.

A series of experiments were conducted on a single-celled organism called Tetrahymena.

Tetrahymena has a useless DNA sequence. After the RNA is transcribed, it will be quickly cut out by itself and then put back together.

According to the experimenter's knowledge, there should be a protein that can recognize this useless sequence and complete the cutting and stitching work.

Then he started his own experiments, putting all the proteins extracted from Tetrahymena together with a section of RNA molecules that had not been cut, and constantly eliminating proteins that did not participate in the shearing process. What was left naturally had the ability to cut.

All functions.

Just keep using the ‘exclusion method’ to find it forcefully.

The experiment went quite smoothly, and the number of proteins was continuously reduced.

However, he later discovered that after removing all proteins, RNA could continue to be cut.

In other words, RNA not only has the ability of DNA to store information, but also has the ability of protein to catalyze.

If a biologically active substance is born due to some accident, but this substance cannot replicate itself in a harsh environment, it will be meaningless and will disappear soon.

Therefore self-replication is considered the origin of living things.

DNA is the manual of life, RNA is transcribed, and it is realized by cooperating with proteins to participate in various reactions.

And the protein itself must have the life manual of DNA first, forming a paradox of which came first, the chicken or the egg.

But if RNA molecules can connect short chains of amino acids together, then all problems seem to 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 you can't verify it, just verify it yourself.

The original anchor point, the origin of the tree of life, the ancestor at the beginning of all spirits...

In 2022, it was proved that RNA molecules can connect short-chain amino acids together, but the time in the book is not yet there, and because magic factors have to be introduced, it will still be different from reality. Don’t blame the author if something slaps him in the face later...

Everything that passes must leave traces.

Even if the words written on a piece of paper are burned, the information about the written content will not be changed.

It's just that the content will be stored in other physical ways.
To be continued...
