What are the key factors to promote the continuous evolution of human beings from Yuanmou people, Beijingers to cavemen?

There are two key factors to promote the continuous evolution of human beings from Yuanmou people, Beijingers to cavemen:

1. Improvement and development of tools: From Yuanmou people to Beijingers and then to cavemen, the tools used by human beings have gradually become more sophisticated and complex. This kind of progress not only improves human's ability to transform nature, but also promotes human's own evolution, including the development of brain and the adaptation of body structure.

2. Evolution of production mode: From hunting and gathering to the development of primitive agriculture and animal husbandry, human beings have gradually mastered more production skills and knowledge. This change not only changed the way of life of human beings, enabling them to make better use of natural resources, but also further promoted the progress of human society and provided more impetus for human evolution.

Generally speaking, the improvement and development of tools and the evolution of production methods are the key factors to promote the continuous evolution of human beings from Yuanmou people, Beijingers to cavemen. With the passage of time, the role of these factors has been continuously strengthened, thus promoting the continuous development of mankind.
