How did humans evolve?

The evolution of human beings originated from forest apes and gradually developed from primates after a long evolutionary process. It has experienced four stages: ape-man, primitive man, homo sapiens and modern man.

Due to the development of modern archaeology, prehistoric civilization has been gradually denied, and archaeology has already had most evolved ape fossils. With the discovery of modern biology, it is found that genetic DNA is evolutionary, which confirms the authenticity of quasi-neutral evolution theory.

Extended data:

Forest apes lived12 million years ago. Their physical characteristics are between apes and humans, and their limbs bones have not been specialized, so they can develop in the direction of modern apes and modern humans.

Tens of thousands of years later, ancient humans began to make more and more complex tools, and at the same time used fire to promote the development of the brain. The brain capacity gradually increased, and finally consciousness sprouted and language was produced, completing the first step of the transition from apes to humans.

Engels classified them as the first of the three stages of human formation, that is, "the group of apes climbing trees." During this long period of time, labor played a decisive role. Since then, culture, art, religion and so on have appeared, and gradually developed into human beings.
