1. Progress of stone tools: In the Neolithic Age, people began to use more sophisticated stone tools, such as stone axes, stone hammers, stone knives, etc. The production technology of these tools has also been improved, enabling people to hunt, collect and process food more efficiently.
2. The rise of agriculture: In the Neolithic Age, people began to use agricultural production methods to plant crops such as grains, vegetables and fruits, which enabled people to obtain more stable and abundant food sources.
3. The emergence of settled life: With the rise of agriculture, human beings began to settle in fixed places, build houses, store food, etc. This settled life also promoted the development and progress of society.
