Dinosaurs are extinct, and the history of human civilization is only a few thousand years. What happened in the blank period?
Compared with the long evolutionary history, thousands of years of human civilization history can be described as "fleeting". 65 million years ago, the dinosaurs that dominated the earth for 200 million years mysteriously disappeared. Will the earth have a blank period after that?

The answer is obviously no, the period from 65 million years ago to 1 10,000 years ago is the Cenozoic in geological age, and the Cenozoic is divided into Early Tertiary and Late Quaternary. About 540 million years ago, modern life began to appear.

In the following more than 53 million years, there was an explosion of life in CAMBRIAN, and almost all kinds of ancestors suddenly appeared. About 450 million years ago, primitive vertebrates appeared and the biological world changed greatly.

In the next 40 million years, insects and amphibians rose, vertebrates developed rapidly, and modern fish teleost began to develop. About 250 million years ago, a large area of forests entered the coal-forming period.

200 million years ago, dinosaurs came out, the supercontinent began to split, the Atlantic Ocean formed, Africa split from South America, and India moved to Asia. The Jurassic period from10.40 billion to10.90 billion was the heyday of dinosaurs.

The period of 70 million years after 65.438+0.4 billion years is called Cretaceous. The continent was separated by the ocean, the earth became dry, and many new dinosaur species appeared. The earliest snakes and bees and small mammals also began to appear.

65 million years ago, dinosaurs became extinct. This is the fifth mass extinction since the birth of the earth. Dinosaurs once ruled the earth for 200 million years. There are nearly ten thousand kinds of dinosaurs in the world, including the polar regions.

The reason why dinosaurs suddenly disappeared has become an eternal mystery. The reasons for extinction are not detailed in this article. After the extinction of dinosaurs, primates, our distant ancestors, began to appear on the earth.

Twenty-five million years after 60 million years ago, the earth was in the Eocene geological age of Tertiary, and human beings were still in the age of apes. 35 million years ago, the earth entered the Tertiary Oligocene geological era, and human beings entered the group of ancient apes.

25 million to 3 million years ago, the long process of apes parting began. From 25 million years ago to120,000 years ago, a long process of transformation from apes to humans began, which lasted for the next 9 million years.

From 3 million to 6.5438+0 million years ago, the Paleolithic Age of the pre-ape clan society began. Early apes have learned to use natural fire, but they can't save kindling. Two million years ago, Australopithecus appeared.

654.38+07500 years ago, apes entered the stage of being able to do things. 654.38+0000 to 300000 years ago, human beings were still in the Paleolithic age of the pre-ape clan society, and the late apes were able to control and preserve natural kindling.

10.5 million years ago, the population began to expand, and early agriculture appeared four thousand years later. 8,000 years ago, China's farming civilization began to breed. In BC 1300, Pan Geng moved to Yin, and Chinese farming civilization was declared open.

In the evolution of more than 60 million years, fire has played a vital role. From 1 10,000 years to 200,000 years ago, there were many human beings on the land of China, and the Beijinger who lived 500,000 years ago was one of them.

In the strata where Yuanmou man's fossils were found, a large number of carbon chips appeared, and some carbon-bearing layers were more than three meters thick. "Beijingers" evolved from apes have been able to completely control natural fires, use and preserve kindling.

According to documents, Suiren invented drilling wood to make fire, which was a clan that originated from Haidai nationality in the east and was in matriarchal clan commune at that time. About 8000 years ago, the farming civilization in the Yellow River Basin began to sprout.

Haidai people who mastered fire in the East were the first to develop. Besides using fire, they also studied snakes well. They observed the four seasons of snakes and found some solar terms in spring and summer. Snakes are regarded as clan totems.

The invention of drilling wood for fire is of great significance in the history of human evolution, which ended the era of human eating meat and drinking blood. In the late primitive society, human beings had some simple norms to restrain each other's behavior.

This is the earliest ritual system, which originated in Xiang and was named after the Yellow Emperor. The etiquette of later generations did not come out of thin air. It took thousands of years from the Five Emperors to the Spring and Autumn Period before it finally rose to the height of theory.

From the late primitive society of Three Emperors and Five Emperors to the slave society of Xia and Shang Dynasties, and then to the feudal society after Qin Dynasty, Chinese civilization has gone through more than 5,000 years. Humans, including civilizations, did not suddenly appear, but all experienced a long evolution, and there was no blank period in the whole process.

To sum up, after the extinction of dinosaurs, apes began to appear. After tens of millions of years of evolution, apes began to separate, and not all apes can evolve into adults. After human beings separated from southern apes, they finally completed the evolution of apes, entered primitive society, and then developed into slave society.
