About 50 million years ago, primates evolved rapidly in a radial way, and then they were differentiated from lower primates (such as lemurs and tarsiers) to higher primates (namely apes, such as macaques, golden monkeys, baboons and apes).
Australopithecus first appeared in eastern and southern Africa, evolved from primitive apes and differentiated into lower apes (such as gibbons), higher apes (such as orangutans) and ancient apes.
Extended data:
1, early ape-man stage. Living about 3 million years ago to 6.5438+0.5 million years ago, it has the basic characteristics of human beings. It can walk upright and make simple gravel tools.
2. Late ape-man stage. About 2 million to 300,000 years ago, they had human-like bodies and huge brains, could make more advanced paleolithic tools, and began to use fire, such as Peking Man in Zhoukoudian, China.
3. Early Homo sapiens (the ancients) stage. From10-200,000 to 50,000 years ago, it gradually broke away from the characteristics of apes and became very close to modern people, such as Neanderthals in Germany.
4. Late Homo sapiens (newcomer) stage. About 40,000-50,000 years ago, at this time, the evolution of human beings has obviously accelerated, and it is very similar to modern people in form. Culturally, the art of sculpture and painting appeared, and decorations appeared.
