When did early human civilization appear in Africa and Europe?

In Africa and Europe, there are two different views on the earliest time of human civilization. One is the African origin theory dominated by foreign scholars, which is based on the fact that paleontologists believe that the earliest hominid fossil-Australopithecus (early ape) was only found in Africa, so Homo erectus (late ape) in Europe and Asia should have migrated from Africa about 2 million years ago. According to the investigation of various human genes on various continents in recent years, foreign biologists have come to the conclusion that people all over the world migrated from Africa around 200 thousand years ago. One theory is based on a large number of paleontological fossils and the shortcomings of African theory, which holds that China scholars mainly believe that the birthplace of human beings is in Africa and also in East Asia. On the basis that East Asia is also the birthplace of mankind, China scholars have recently further proposed that Jiangsu and Anhui are one of the birthplaces of mankind.

When did human civilization first appear in China, West Asia, Africa and Europe? What's its name? What are the representative achievements? Civilization should be said to enter the civilized era at least after the emergence of cities. The first few just talked about the origin of human beings, when human beings were far from entering the civilized era, which had nothing to do with your question.

Here are my thoughts:

Africa: Egypt: A city-state appeared around 4000 BC, which was eventually divided into Upper Egypt and Lower Egypt. After menes's reunification, Egypt's representative achievements include pyramid of khufu, the Sphinx and Egyptian hieroglyphics ... When Egypt's Thutmose III, Egypt became a great military empire across Asia and Africa with great force. ...

West Asia: Babylon: Around 4500 BC, the two river basins were controlled by Sumerians. King Hammurabi of Babylon promulgated the code of hammurabi. Later, people in the two river basins set up hanging gardens, but the hanging gardens have long since disappeared. The ancient Babylonian civilization is the only one among the four great civilizations that has not survived. After being ruled by Assyrians and Persians, it was placed under the rule of Alexandria ... and finally civilization disappeared. ....

China, founded in the Xia Dynasty around 2500 BC, has continued to this day. Compared with other civilizations, China culture has continued and created many representative achievements: bronzes in Shang Dynasty; The feudal system, ritual and music system and patriarchal clan system in Zhou dynasty; The Great Wall, the Forbidden City, the four great inventions ... and many famous people. China's civilization is the most splendid.

European civilization is guided by ancient Greek civilization: ancient Greek civilization, also known as marine civilization, can be divided into Crete civilization, Mycenae civilization and Greek classical era. The earliest Crete civilization was not established as early as the Xia Dynasty in China. The representative achievements of ancient Greek civilization: although the democracy in Athens was not perfect and limited to a small city-state, it pioneered the western democracy; There were many famous people in ancient Greece, and their achievements also represented the achievements of ancient Greece, such as Socrates Plato Aristotle Archimedes.

Aristotle: initiated logic and put forward syllogism; His thoughts are close to materialism. ....

Archimedes: A typical example is the buoyancy theorem.

I've been calling for a long time, and I hope you can accept it satisfactorily.

When was the earliest human civilization in China, West Asia, Africa and Europe? What's its name? What are their representative achievements? 6000 years ago

The earliest dawn of European civilization is (). The Kart Island civilization and Mycenae civilization in ancient Greece are the synthesis of Aegean civilization.

Did human civilization originate in Africa? According to current data, yes!

When was the earliest human civilization in China, West Asia, Africa and Europe? What's its name? What are their representative achievements? Ancient China, 2070 BC, four great inventions;

Babylonia, in 3500 BC, wrote on the blackboard and code of hammurabi, divided the year into 12 months and ***354 days based on the moon's profit and loss, and invented the leap month, placing it in 1 1 day different from the solar calendar. Divide an hour into 60 minutes and take 7 days as a week. He can also calculate fractions, add, subtract, multiply and divide, solve quadratic equations with one variable, and invent 10 decimal method and 16 decimal method. They divided the circle into 360 degrees until π was close to 3. Even calculate the area of irregular polygons and the volume of some cones.

Ancient Egypt, 3200 BC, pyramids;

In ancient India in 2300 BC, the so-called Arabic numerals actually originated in India and only spread to the west through Arabs. In the 6th century BC, Buddhism came into being in ancient India. "caste system"

Why did mankind originate in Africa, but there is no splendid human civilization in Africa? I think two very important factors are 1, bad environment and frequent civil wars.

When did humans first appear? Stone age, post Cretaceous, after the extinction of dinosaurs.

When did the real existing multi-color prints in Europe first appear? They first appeared in Britain at the beginning of18th century, and were invented by the Englishman Jacob Christopher Lablanc.

Many printmakers try to blend color into prints. In addition to the early hand-painted woodcuts, woodcut light and dark overprint was also popular in the16th century. Seegers printed monochrome and multicolor versions. But there has never been a real multi-plate color printing, and copper plate printing is particularly difficult because it is difficult for engraving lines and etching lines to overlap colors. Only by inventing a plate-making method that can express multi-level and large gray scale, such as Merudin method and flying dust method, can it be possible to overprint multiple plates. The first person who studied and explored this method and achieved results was an Englishman, Jacob Christopher Rabren 1667- 174 1. Using Newton's light analysis principle, he made three boards with Merosin, which were printed on a black master with three colors: red, yellow and blue. Although the color analysis method and ink quality at that time could not reach the present color printing products. But in the end, it was color printing, which surprised people at that time. With this success, LabBraun opened a LabBraun company in London, England on 1720, specializing in printing color prints. However, 1732, the company went bankrupt and he came to France penniless. But he obtained a patent for color printing in France and was authorized by Louis XV to make a statue of the king.

Until the end of18th century, color plate making was mostly based on Labron's analysis method, but printing technology has made great progress and the quality of printed products is more exquisite. For example, the French sculptor John Raphael Smith (1752- 18 12) printed portraits and genre paintings in Merutin color edition. Bonet, who is good at copying chalk paintings with iron frames, copied Boucher's toner strokes with iron frames of multiple colors, which is very realistic. Louis Filiber de Bookout (1755- 1832), a representative painter of neoclassicism, printed genre paintings that reflected the daily life of Parisian aristocrats, such as A Public Walk in the Palace Garden and He Won't Come.
