The first step, the transition from apes to humans, experienced two stages: Lamarck and Australopithecus.
In the second step, human beings developed to the primitive commune period and became complete human beings, which experienced four stages: early homo erectus, late homo erectus, early homo sapiens and late homo sapiens. It is generally believed that labor plays a decisive role in the process of apes becoming people. There are still many arguments about the origin and evolution of human beings in academic circles.
