In the flickering firelight, there is a hint of thick brilliance, which seems to illuminate everything, perhaps just to color the picture, to rejuvenate this era that can only exist in the black and white world.

Before this color, there was a stone tool, and the one holding the stone tool was Wang Yang, who looked at the stone tool carefully, and countless thoughts flashed through his mind like electricity, as well as in his opinion, the memory fragments that had been covered with a layer of gray.

The shard was so dull that it didn't reflect any luster at all, and it didn't know what it once was.

But at this moment, Wang Yang's eyes are like a computer, inputting the code representing the color into his brain, trying to reassemble the fragments and glow.

So gradually, the stone tool had its brilliance, and the memory fragments had its brilliance.

I saw that two-thirds of the stone tool was an irregular circle of a can, with pits and depressions, but when I thought about it, when those people made it, they hoped that it was round, because this is the place where the hand is held.

Further ahead, it is much sharper, some like a cone, but in fact, at the tip, it is not a cone, but flat.

If you look further ahead, you can see that those flat ports are actually very sharp, and when you touch your fingers on them, you can feel the jerky touch of the skin being scratched.

It is evident that this is a stone tool that has been beaten, and it is a very good stone tool, with typical chipping in the stone face, which does not give in to the stone cones of the tribe.

But the stone cone is not finely polished, usually a stone that already has a half edge and then another stone is knocked out in half. And even more.

It should be said that this is a very wasteful practice. Because to process a stone cone, it is necessary to waste a very good stone knife embryo.

But Wang Yang appeared after this world. He changed the method of making a stone cone, he would draw a dotted line, and then take other stones and break the dotted line.

To ensure that the other half was also well preserved, it became two stone cones, and then he carefully knocked and grinded, but it looked a little delicate.

In terms of the degree of refinement, it is naturally good for the stone tools after Wang Yang's improvement. But if Wang Yang hadn't crossed here, the weapons of those "giants" would have been very exquisite.

At least in this era, it is a good weapon of the first class.

The stone tool now in Wang Yang's hands is not a stone knife or a stone cone, but a stone axe.

The concept of the axe, which has been deeply rooted in the hearts of the people since the early days, is a long handle made of wood, and the tip is a sharp iron. It is completely different from the "axe" in front of you.

But this is the stone axe, at least that's what the scientific name says, even though it looks a lot like a grenade.

Wang Yang recognized the hand axe. Because it's so famous, spanning an incomparably long era.

This is one of the representative tools belonging to the Acheuri culture, the hand axe.

Humanity in evolutionary history. There have been several cultures. There is an Olduvai culture that belongs to the era of capable people.

The characteristic of the Olduvy culture is that it takes two stones. Hitting each other is generally like splitting bricks by hand.

Everyone knows the bricks. They took a stone first and held it as a brick, and with the other hand they took another stone and split it at the stone which was taken as a "brick," and the stone was cut in half, and there was a sharp edge.

This is a very primitive stone tool processing, basically the same as what Wang Yang saw, and the stone cone is also processed in this way.

These are the Olduvi culture, very primitive and clumsy, but they are the beginning of civilization and do not last long.

After the Auduvi culture, the longest paleolithic culture of mankind came, which is the Acheuli culture.

The Acheeri culture began about 1.7 million years ago and flourished for a full 1.5 million years until 200,000 years ago.

The horror of the duration, from the late stage of Homo sapiens, across Homo erectus, to the early stage of Homo sapiens, has gone through the evolution of three major types of human races!

During this period, there were countless human races and subdivisions that appeared and became extinct, which can be called the most in the Paleolithic Age.

You must know that the talented people have just left the category of academic apes, and they are already very pure people, but in the hearts of modern people, humans in this period are still apes.

To be precise, it should be primitive man, and ape-man is another half-human primate, half-ape and non-ape, and I don't know how Lu Dao joined the ranks of primitive man.

It started from such a group of extremely primitive humans, who were still ape-man in the hearts of humans, and continued through the great age of Homo erectus, and finally entered the early Homo sapiens.

What is Homo sapiens? Modern man is Homo sapiens!

It is an unbelievable thing that a culture can flourish from primitive humans to early Homo sapiens.

Its horror is as great as it is huge, and it can be seen.

So what is the reason why human beings have been living in this culture for millions of years? Could it be that there is something fascinating about this culture?

The answer is, no!

Although this period of culture takes a long time, it looks magnificent, majestic, and high-spirited, and can cross the Yalu River.

But in fact, the content contained is incomparably scarce, there is not much special, a bit like the Chinese hoe, a hoe appeared thousands of years ago, and thousands of years later, the hoe is still the same hoe.

Stone culture basically took hundreds of thousands of years to make more progress, and then stagnated for hundreds of thousands of years, and then went further.

It wasn't until the advent of Homo sapiens that it developed rapidly.

In the whole culture, the development of stone tools gradually changed, and a more detailed and elaborate period of making suddenly arrived.

In order to meet the needs of a better living environment, face more wild animals, adapt to the changes in the ecosystem, and the transformation of food composition.

As a result, in the late Homo Nengren, the first stone tools with the characteristics of the Acheuli culture appeared.

The hand axe is one of the most distinctive stone tools.

It is a complex stone tool that has been carefully beaten, easy to use, but complex, to be carefully beaten, thin, sharp, is the stone tool symbol of the Acheulian culture.

At this time, humans have realized that thinner blades have more powerful damage.

And the person who invented this kind of stone tool is a capable person, a person who carries it forward, a person who is erectus, a person who eliminates progress, and a person who is Homo sapiens.

It seems that these three types of people are still inseparable, and it seems that the identity of that group of "giants" is still unclear.

However, according to the research of various archaeologists, from 1.8 million years ago to 1.7 million years ago, there was already a human race that began to make such stone tools in large quantities.

This human name is called "Craftsman"!

"Craftsman!" Wang Yang finally remembered, his eyes flashing brightly. He was not surprised by the Acheeri culture that appeared at this time, saying that he lived about 1.7 million years ago, and he lived about 1.8 million years ago, which is not nearly 10,000 years before and after.

"It's only tens of thousands of years...... Hey? What do you mean by tens of thousands of years? I can't live that long. Wang Yang felt very painful, a generation into history, I feel that it is not a problem if I haven't gone for hundreds of millions of years.

But his lifespan is less than 100 years, and it is estimated that he will hang up in a few decades, which is very contradictory and speechless.

Straight to the point.

Human beings are divided into species and named, which is very interesting, for example, capable people, capable people, and skillful people.

Homo erectus, a person who walks upright.

Homo sapiens, wise people.

A craftsman, on the other hand, is a person like a craftsman.

The origin of craftsmen is actually very interesting, but also very boring, originally there were no craftsmen, but in the late stage of the Homo sapiens, there will always be human migrations.

The earth, for example, always comes out of Africa.

The two places have been separated for a long time, they have never intermarried, and the different cultures and environments have different evolutionary choices.

As a result, there are various distinctive races.

In the year 1.8 million, to 1.7 million years ago, this period was a very peculiar period, this period of people were more than one race, there were capable people, there were Homo erectus, and craftsmen.

According to the narrative of a certain point of view, the evolution of human beings is roughly divided into Australopithecus, Homo sapiens, Homo erectus, and Homo sapiens.

These are the four main categories.

And there is a doctrine that it is a capable man, a craftsman, a Homo erectus, and a Homo sapiens.

This kind of doctrine is not very credible, and not many people support it, and Wang Yang does not believe it.

Because the extinction time of Homo erectus was about 1.7 million years ago, and the appearance of Homo erectus was 1.75 million years ago, just right, when Homo erectus was about to become extinct, Homo erectus appeared.

The appearance of craftsmen was 1.8 million years ago, and the extinction time was 1.4 million years ago.

In other words, craftsmen appeared in the late Homo erectus period, tens of thousands of years earlier than Homo erectus, which is also the basis for those who support that craftsmen are the ancestors of Homo erectus.

But why don't they think about it without that damn brain, the craftsman was extinct 1.4 million years ago, and coexisted with Homo erectus for hundreds of thousands of years, if it really evolved like this, it can evolve for hundreds of thousands of years?

Therefore, the brain cells of those guys are more precious than Wang Yang's brain cells, and they are reluctant to kill some.

Wang Yang is quite confident, why? It can refer to the time when Homo homo replaced Australopithecus, and the time when Homo sapiens replaced Homo erectus.

It's not more than 200,000 years, and no one else has wasted so much time evolving.

According to Wang Yang's guess, craftsmen, like Homo erectus, are all capable people who evolved, but Homo erectus ruled the world and continued, but the craftsmen were eliminated.

Becoming a king or defeating a king, since it is an eliminated race, there are naturally few opportunities for craftsmen to appear in front of the world, so Wang Yang thought about it for so long before he thought of this group of tragic babies.

"It turned out to be a craftsman...... Wang Yang narrowed his eyes, craftsmen were just a branch in the evolution of human beings, and no one was interested in paying attention to how they became extinct.

During the period of their extinction, there were no particularly dramatic environmental changes, and they were not famous at all.

Seriously, Wang Yang is not very interested in them, they are really a tragic group of people.

Or the Neanderthal scenery of later generations, when they became extinct, a series of large and small animals such as mammoths, saber-toothed tigers, saber-toothed tigers, etc., were buried with them, and the scene was called a scenery, which was more luxurious than the emperor's funeral.

Now, the "tragedy" is in front of your eyes, how to deal with it? (To be continued......)
