What is the history of human development?

The process of human development is generally divided into four stages:

Early ape-man stage.

Late ape-man stage.

Early homo sapiens stage.

Late homo sapiens stage.

According to fossil data, from ape to human, it has gone through four stages: drypith-cus-cus-Cus, Ramapithecus, Australo-pithecus and Homo.

Forest Australopithecus flourished in Europe, Asia and Africa in the late Oligocene and the middle Miocene, and was the ancestor of various existing apes. Lamarckian apes evolved from forest apes about150,000 years ago and lived between150,000 and 8 million years ago. This fossil was first discovered in Keshan, Seevali (1932), and later found in Africa, Europe and Yunnan, China.

It is generally believed that Lamarcinopithecus is an early representative of the transition from apes to humans and the earliest member of Anthropology. However, the newly discovered fossils in recent years have increased the suspicion that Raemakers is a primitive man, and some people think that he is a progressive ape.

Australopithecus fossils were first discovered in South Africa (1924). Australopithecus lived about 3 million ~/kloc-0 million years ago, and its primitive type may be the representative of the late transition stage from apes to humans. From Australopithecus to modern man. Labor plays an important role in the evolution from apes to humans. Because of labor, the posture of the body changed from semi-upright to upright. Labor and language promote the development of the brain, which accelerates the transformation from apes to humans.
