1. Artificial lighting is the embryonic form of energy technology, audio language is the embryonic form of information technology, and stone tool making technology is the embryonic form of machine manufacturing technology.

2. The development of the three technologies laid the foundation for the origin and development of civilization.

3.65438+5000 years ago, the Paleolithic Age turned to the Neolithic Age, the last glacial period of the Quaternary ended, the global climate began to warm, the Eurasian ice sheet was replaced by forests and grasslands, and Africa also changed from rainy to dry. A generation in southern Europe and western Asia began to experience mild weather similar to today. Many large paleolithic animals became extinct, mammals and birds living in forests increased, and human hunting objects began to change.

4. Changes in economic activities have promoted changes in tools. The invention and use of attack weapons and bows and arrows promoted the development of human hunting.

5. The agricultural revolution took place in the Neolithic Age and originated in West Asia. About 9,000 years ago, crops such as barley, wheat and lentils were planted in Mo Ye area in northern Iraq. There are also traces of crops in Jericho in the Jordan Valley. The reason why it became the birthplace of agriculture is not only its geological, climatic and animal and plant distribution characteristics, but also its connection point with Asia, Europe and Africa.

6. Earlier, traces of crops were also found in East Asia and South America. In Central America and Mexico, in 5000 BC, corn appeared. ...

7. The most important symbol of the agricultural revolution is the artificial cultivation of plants and the artificial domestication of animals.

8. Primitive agriculture characterized by artificially cultivated plants developed from gathering economy.

9. Animal domestication and agricultural cultivation were in the same period.

10. Food gatherers have gone too far for food producers.

1 1. The agricultural village appeared, representing the Iraqi Mo Ye.

12. The urban revolution is accompanied by the use of metal products.

13. There was a transitional period in which the Neolithic Age was replaced by metal products, which was called the Stone Age, the Bronze Age and the Iron Age.

14. BC 1400, iron-making technology was invented, and Hittite Kingdom was the first country to invent iron-making technology in the world.

15. With the emergence of agriculture and the progress of production tools, the form of human production organization has quietly changed and settled in areas suitable for agricultural production and close to water sources and cultivated land.

16. Due to the contradiction and conflict between water source and production necessities, the settlement conflict turned into war, so the settlements began to merge.

17. With the development of production technology, surplus products began to appear.
