The origin of civilization depends on climate. If civilization originated from ice sheets similar to those in Antarctica, would you believe it? I don't believe it. After all, this is not transferred by human will. Without food or drinking, it is impossible to survive at all.
The above figure is the glacier-shaped sea level change curve for nearly 130,000 years. The number on the horizontal axis is the time from the present. Looking from the left to the right, it can be clearly seen that the severe cold period was only declared 11,700 years ago. Entering the late ice stage.
In other words, 18,000 years ago, the earth was in the peak period of the ice age, in the middle and high-dimensional areas, and the entire ocean was frozen for several meters or even hundreds of meters, and no nation could survive.
11,700 years later, the temperature gradually rises, the medium and high-dimensional areas gradually thaw, and everything revives. The first thing to thaw is the coastal areas, because the ocean is connected, and ocean currents will bring warm sea water near the equator to medium and high dimensions.
It is after this time that civilization gradually comes to us.
A large number of Paleolithic stone tools and a large number of mammalian fossils were unearthed at the Paleolithic site in Sanshan Island in Taihu ;
Nearly 200 jade artifacts were excavated in the Xiaonanshan site of Raohe, Heilongjiang, Northeast China. This is the earliest one. Jade, pushing the appearance of jade to about 9,000 years ago;
Ningbo, Zhejiang Hemudu is a clan village site during the Neolithic matriarchal commune period (about 7,000 years ago), and a large number of "htm" was found in the ruins. l5 dry railing style The ruins of the house.
The remains of the Majiabang cultural period are found in the soil samples of He Village, Meili Town, Changshu City, more than 6,700 years ago.
As the temperature further rises, the inland areas gradually thaw, and civilization began to expand from coastal to inland. Four thousand years ago, prehistoric civilizations such as Yanhuang and Xia formed.
people, after all, are mammals, the temperature is minus 60 to 70 degrees Celsius, and then the primitive people can be born, which is too wishful thinking.
