"Brother Chen, you are an expert in this field and have a wealth of knowledge, can you tell us about these rock paintings?" Sun Yue said to Chen Rui.

"Absolutely." Chen Rui nodded and said, "You see, there are fish, deer, goats, buffalo and mammoths in the petroglyph patterns, as well as the patterns of saber-toothed tigers, which can show that an ancient primitive tribe once lived here, making a living by fishing and hunting, and competing with mammoths, saber-toothed tigers, wolves and other fierce beasts for survival resources, and living a primitive life of fur and blood. ”

Also, here, some lines depict piles of firewood with fire on top of it, which tells us a very important message that this primitive tribe has learned to use fire. The use of fire, which was a very big advance for primitive civilizations. ”

Chen Rui explained some of the meanings of the petroglyph patterns to Li Wanhao and the others, while watching other petroglyphs.

The petroglyphs give very limited information.

Chen Rui was able to draw a few points from these petroglyphs, about the primitive tribes that once lived here.

1. Be able to use simple tools, for example, it is very simple to use the method of hitting stones to make scrapers, sharpeners, choppers and other tools.

2. Fire will be used.

3. Fishing, hunting, and gathering wild fruits for a living.

4. This primitive tribe that once lived here is facing very great dangers, fierce saber-toothed tigers and wolves, bears, mammoths and other wild beasts, gathered in the forest, haunted in the mountains, not only threaten their safety at all times, but also, these beasts compete with the primitive tribe for limited survival resources.

These are enough to show that the primitive tribes that once lived here were 'people', 'fully formed people'. And not apes.

That's a very big piece of information.

It is important to distinguish between 'man' and 'ape'.

Everyone knows that man evolved from apes.

65 million years ago. A meteorite about 16 kilometers wide struck the Yucatan Peninsula in present-day Mexico. At that time, two-thirds of the animal species on the planet, including dinosaurs, died out and became extinct, the golden age of reptiles ended, and primitive mammals survived for a long time, and then evolved rapidly.

More than 50 million years ago, primates evolved rapidly in a radial manner, and higher primates were differentiated from lower primates protomonkeys.

Next, the ape appeared.

Apes appeared 33 million to 24 million years ago, giving rise to apes from Old World monkeys.

Between about 10 million years ago and about 380 or 2 million years ago. Two famous apes were produced on Earth. One is Ramaucus and the other is Australopithecus.

Among them, the most famous is Australopithecus.

Australopithecus is known as "Man in the Making".

2.5 million years ago, Africa's climate began to deteriorate, and the ice age hit from the Northern Hemisphere, and most of the Australopithecus disappeared.

However, there are two exceptions, one is that in some areas the savannah remains, where the australopithecus survived.

Another scenario is: Australopithecus was forced to become smart and use their ingenuity to survive. Learn to throw stones, use wood, make primitive weapons, use campfires, and of course they are not 'human' yet, but will eventually evolve into a human genus.

Homo erectus appeared next on Earth, and Homo erectus was a 'fully formed man' who knew how to use fire, began to use symbols and basic language, and was able to use more refined tools.

Compared with the Australopithecus australopithecus who was forced to become smarter, they simply learned to throw stones and use wood, and Homo erectus adopted the method of hitting stones with stones, touching anvils, smashing stones, chopping branches, and making tools, which were indeed more refined tools.

With the limited information given by the guò petroglyphs, Chen Rui can basically determine that the primitive tribe that once lived here was Homo erectus.

The age may be more than 2 million years old to more than 210~2.2 million years.

Because, there is evidence that the Sahara Desert was formed more than 2 million years ago, and the Sahara Desert more than 2 million years ago was a verdant grassland dotted with lakes and ponds.

If, there were once primitive tribes living here, there were enough food sources, and a good living environment allowed them to survive here.

That was only before the formation of the Sahara Desert, when the Sahara Desert was still a verdant grassland.

Remains of Homo erectus' life more than 2 million years ago!

There are also a lot of petroglyphs left by Homo erectus more than 2 million years ago on the rock wall.

In fact, there are more surprises waiting for Chen Rui to discover, such as the fossilized bones of Homo erectus living here.

If it is announced, it is estimated that the archaeological community and academic circles around the world will shake the N circle.

For example, the Yanjing ape-man, scientifically known as 'Yanjing Homo erectus', came to Zhoukoudian about 700,000 years ago, lived here for nearly 500,000 years, and left about 200,000 years ago.

The discovery of Yanjing ape-man, the announcement of this news, shook the world's academic circles.

In China, the famous Yanjing skull, the legend and mystery surrounding this thing and the mystery of its whereabouts are estimated to be written in a biography of tens of thousands of pages.

And Homo erectus who used to live here was more than 2 million years ago.

If the influence level of Yanjing ape man can shake the archaeological community and academic circles around the world.

Well, the level of influence of Homo erectus found here can shake the archaeological community, the academic community around the world 4 times.

If you compare it by seismic magnitude.

The earthquake that Yanjing apes gave to the whole world was a magnitude 10 earthquake.

The Homo erectus here shook the world with an 11-magnitude earthquake.

The significance of the discovery of the skull of Yenjing Man is to confirm the existence of Homo erectus, clarify the sequence of human evolution, and provide strong evidence for the theory of 'from ape to man'.

Here Homo erectus found that the meaning was more important.

You must know that more than 2 million years ago, in the history of human evolution, it was a very special period of time.

During this time, due to the deterioration of the climate in tropical Africa, Australopithecus was forced to begin to evolve from apes to humans, adapt to the environment, and survive.

During this time, Homo erectus, who had just evolved from Australopithecus, was once again forced by the harsh environment to embark on the first great migration, spreading from Africa to Asia.

The earliest representative of the African Homo erectus germ lineage is the Zhuang man.

The discovery of this life relic can tell the world that Zhuang Man is not the earliest Homo erectus lineage, but the unnamed Homo erectus found by Chen Rui here.

It directly pushed forward the history of Homo erectus by 20 or 300,000 years.

Petroglyphs are only part of this living relic. (To be continued......)
