What was it that humans came to Germany in the first place? What did it evolve from?

Where did humans come from, and there are doubts about human evolution.

Man evolved from apes.

In the evolution from ape to man, social activities played an important role, including social labor and the interaction between different individuals in the process of labor. Through the way of life such as gathering and hunting, complex forms of group organization were established. The social relationship of close interdependence and division of labor and cooperation between individuals in the group has been established, and an increasingly complex social organization has been established.

At the same time, language is needed for social activities, and language is used in all aspects of life, and writing is gradually developed, which promotes communication and exchange between people. At the same time, on the basis of language, there is a social culture, and the use of language and writing plays a crucial role in the evolution of the brain.

In the process of primate evolution, organisms are in an increasingly complex social structure, survival experience is accumulated and transmitted through the group from generation to generation, and the complex individual relationships in the group produce various physiological and psychological experiences, all of which promote the perception and cognition of life for nature and self.

Through the influence of complex behaviors and social activities, primates gradually distanced themselves from ordinary animals in terms of intelligence, and embarked on the road to a higher form of life.

Complex social activities have created human culture, which in turn has promoted the formation and development of human intelligence. It has taken a long time from the evolution of primates to humans, and this process is also the process of the development of primate intelligence, or the accumulation process of life's knowledge of nature and self, and the rapid development of intelligence is the key factor that contributes to the differentiation of some primates from ordinary animals.

1. Early ape-man stage: It lived about 3 million to 1.5 million years ago, and already had the basic characteristics of human beings, able to walk upright, and make simple gravel tools.

2. Late ape-man stage: about 2 million to 300,000 years ago, the body is like a man, the brain is large, can make more advanced paleolithic tools, and began to use fire, such as the Beijing ape man in Zhoukoudian, Beijing, China.

3. Early Homo sapiens (ancient people) stage: 10-200,000 to 50,000 years ago, gradually detached from the characteristics of apes, and very close to modern humans, such as Neanderthals in Germany.

4. Late Homo sapiens (new man) stage: about 4-50,000 years ago, the evolution of human beings at this time has accelerated significantly, and it has been very similar to modern humans in form. For example, in 1933, the cave man on the top of Zhoukoudian Keel Mountain was discovered.

At this time, primitive religions had already arisen and had entered a matriarchal society. In the late Homo sapiens stage, modern humans began to differentiate and form, and distributed all over the world The origin and development of human beings is a very complex issue, although after the efforts of Darwin and others and more than 100 years later, there are still different opinions and questions. Humans first evolved in Africa, and most of the evolution of humans took place on the African continent.

Because the fossils of early humans who lived between 6 million and 2 million years ago came entirely from Africa. Currently, most scientists know about 15 to 20 different species of early humans. However, scientists are not entirely consistent in their understanding of the relationship between these species and which species are extinct.

Many early human species, most of which did not leave any surviving descendants. Scientists are also debating how to identify and classify specific species of early humans, as well as the factors that influenced the evolution and extinction of each species. The earliest migration of early humans from Africa to Asia was probably between 2 million and 1.8 million years ago.

They entered Europe relatively late, between 1.5 million and 1 million years ago. The species of modern humans only appeared in many parts of the world much later. For example, people may have first come to Australia in the last 60,000 years, and the Americas for the first time may have been around 30,000 years ago.

Evolved.

Darwin's theory of biological evolution holds that humans are the product of biological evolution, and that modern humans and modern apes share a common ancestor.

In ancient times, the origins of human societies on various continents diverged. The early domestication of wildlife in China, Central America, the southeastern United States, and other regions gave ethnic groups in these regions a head start.
