What is reasonable about the theory of the origin of many places of mankind and the theory of Africa

In the latest molecular science and technology it has been shown that modern man is a group of people who have been away from Africa for about 100,000 years. As for the number of other human genes, it is said that no more origins can be established. In fact, the so-called multiple origins theory is actually the theory that modern humans have multiple origins.

The term was first coined by Warbof, a professor at Missigan University, in the 1980s. Although after the 1990s, there was more genetic evidence, which seems to be more supportive of the single origin theory in human origins.

However, there is still a certain scale of scientists who support the origin of humanity in more than one place. In many local origin theories, human ancestors left Africa as early as 1.5 million years ago, and they began to evolve independently as soon as they lived around the world. These people include Pekingese, Neanderthals, Javanese, and many more.

They adapt to their environment while evolving into modern humans. Although the evolutionary direction of human beings located in different regions is different, the evolutionary direction of modern humans is large due to genes, mutations, etc.

At present, there are two main points of view, one is the theory of multiple origins and the other is the theory of African origins. The theory of multiple origins implies that the origin of humanity is not in the same place, but in many places people have evolved under their own regional conditions to have the current black, white, yellow, and various other races. The African origin theory states that humans first appeared on the continent and evolved to the Homo sapiens stage, then Homo sapiens traveled all over the world and then evolved into a variety of races.

This is also the reason why human beings no longer have local diversity. They share many similarities and have few local features. In addition, two other people in the scientific community have proposed similar theories of human origins, namely the German anthropologist Wei Dunrui in 1930, and the American anthropologist Carlton Kuhn in 1960.

The former believes that it is precisely because of the independent evolution of ancient upright people from various places that human beings have different races.

The rationality of the multi-site origin theory is that the archaeology of hominids in Africa is much longer.

The theory of multi-origin is consistent with the reality of different human races, and the theory of African origin is consistent with the fact that most of the genes in the human body are the same.

The multi-origin theory is plausible because traces of human ancestors have been found in both Africa and Asia. Where the African origin theory is plausible is that archaeological finds of African skulls are much earlier.

This claim exists, and the data suggests that the origin of humanity has not yet been concluded.

At present, the research on the origin of modern man is still in the stage of blind people touching elephants, and it is still only analyzing and explaining local problems and materials, and it is not yet possible to draw comprehensive and universally accepted research conclusions. Technological innovations and research breakthroughs in the field of ancient DNA, especially the deciphering of early Homo sapiens genes in East Asia, are expected to help unravel the mystery of the origins of modern humans.

Regarding the "African theory" of modern people and related discussions, the main evidence** and discourse are based on Africa, Europe, and West Asia. Chinese materials are rarely included in the research horizon, and in particular, the "early Homo sapiens" in the East have been seriously neglected, with great bias and limitations. There are many archaeological discoveries related to the origin of human beings in China, and they have become a sequence, an endless branch, and there is no gap in human evolution between 10 and 50,000 years ago.

In particular, early Homo sapiens fossils, such as "Xuchang Man", have both ancient and modern features. Archaeological discoveries show that China's Paleolithic culture also developed continuously and was passed down from generation to generation.

Humans originated in Africa, which is first confirmed by the large number of fossils excavated in Africa. These fossils include a variety of forest apes, ground apes, ape-likes, and manoidsGreat apes, apes, ancient people, including bones, various stone tools and bone tools, tombs, from 6 million years ago to 10,000 years ago, basically formed a complete evolutionary chain.

Because of the harsh conditions under which fossils were formed, it is also possible that fossils from certain periods were still hidden in unknown places, so there are missing links, but this does not deny the evolutionary history of human beings in Africa.

Humanity is an evolutionary process:

In eastern Africa about 200,000 years ago.

The direct line of modern man.

Ancestors - Homo sapiens evolved. Homo sapiens can run, speak, use fire, craft and improve tools, and are extremely intelligent. So, they soon prospered and then migrated all over the world.

The process was extremely difficult, and they set out several times and failed several times over a period of more than 100,000 years.

Until that time, about 70,000 years ago, it took Homo sapiens 50,000 years to reach Antarctica, relying only on his legs.

all other continents. Human skin color, hair, pupils, and other different physical characteristics are formed in the process of migration and settlement.

About 200,000 years ago, Homo sapiens living in Africa began to migrate to North Africa, reaching the Middle East via the Red Sea or the Suez land bridge, but they did not survive long and disappeared without continuing to migrate further afield. The rationale is that modern Homo sapiens fossils in the Middle East were a blank 200,000 to 100,000 years ago.

By 100,000 years ago, they once again left the Zhizha Africa, and moved from the Middle East to the east, north, west and other directions, and finally distributed to the world. During the migration, it was thought that they did not mix with the local hominid under the possible reproductive isolation, and for some reason they gained an advantage in the competition with the local hominid, which led to the extinction of the local hominid.

In their migration, they mixed with the local primitive race, but compared with the local primitive race, modern humans from Africa still have a competitive advantage, so in the DNA of modern people, Europeans have Neanderthal genes, Asians also have non-African genes, but the genes left by local primitive people account for only a very small amount, and most of them are still genes from African modern people.

The origin of human beings is a question that many great scientists have been exploring, and everyone agrees that human beings evolved from apes, but there has always been controversy about where humans originated from. So for humans, is their origin Africa? What is the scientific basis for this?

Why is it possible that Africa is the origin of mankind? This is because scientists have discovered a large number of early human fossils from Africa in the last century. And this fossil is currently the longestIt also records the changes of the people

It can be seen that human beings have evolved over a long period of time to become the human beings they are today. Therefore, many scientists speculate that people's common homeland is actually in Africa, because whether black or white, all human beings are one species, so the origin of human beings may be in Africa.

But many people speculate that if we really originated in Africa, why did it evolve into the different skin colors of whites, blacks, and yellows, and why only blacks exist in Africa now? It's actually because of the change in skin color、YesDue to the influence of the local environmentIn Africa, black people become black after a long period of exposure to the sun**, and the choice of skin color is also a choice of the society for human beings at that time, at that time, if human beings can not live in Africa, they choose to migrate to various worlds, then their skin color will also change with the climate of the day.

With the current scientific discoveries to prove that Africa is the origin of mankind, only in the last century when scientists found fossils, which show that this is the early representative of Homo sapiens in Africa, that is, the early humans, but I want to uncover the truth about the origin of mankind, nowThere is no way to answer yet, can only leave everything to science, and the continuous exploration of people.

Yes, the origin of apes is in Africa, and according to relevant research, there are some archaeological studies that can be determined.
