Are China people from Africa?

As we all know, human beings have changed from Homo erectus to Homo sapiens, and modern people are late Homo sapiens. Half a century ago, Dunrui Wei, a Jewish anthropologist, the most important scientist who used modern scientific evidence to explore the origin of modern people, put forward that Homo erectus in Beijing was a direct ancestor of Homo sapiens and had the closest relationship with some groups of Mongolian people after studying the fossils in detail. It should be noted that Dunrui Wei also pointed out that his statement does not mean that the modern Mongolian race originated from Homo erectus in Beijing, nor does it mean that Homo erectus in Beijing did not provide sources for other races.

The Mongolian race mentioned by Dunrui Wei refers not only to Mongolians, but also to the yellow race including China, Japanese, most people in Southeast Asia, American Indians and Eskimos. China people, as the main members of the yellow race, are, of course, descendants of Homo erectus according to Dunrui Wei's theory. However, according to the understanding at that time, Homo erectus in Beijing existed about 5, years ago, but only human fossils of Hetao and caveman were found between Homo erectus in Beijing and modern China people at that time, but the last two fossils were less than 5, years old. Therefore, there was at least a long historical gap between Homo erectus in Beijing and caveman in caveman in caveman in China at that time, and there was also a historical gap between caveman in caveman in caveman in modern, but the time was shorter. What happened in these two historical gaps was unknown to people at that time, but in more than 4 thousand years, all kinds of events could happen, such as large-scale migration and migration, extinction of people in some areas and so on. So there was not enough fossil evidence to prove that Homo erectus was the ancestor of modern China people at that time.

until the early days of liberation, as the country broke ground everywhere, many new human fossils and their stone tools emerged. In 195s, new human fossils were unearthed in Ziyang, Sichuan, Ding Cun, Changyang, Hubei, Maba, Guangdong, Liujiang, Guangxi and Wushenqi, Inner Mongolia. Many Neolithic human remains have also been found between cavemen and modern people. All these have filled the gap between Homo erectus and modern people in Beijing and improved the persuasiveness of the ancestral relationship between them.

However, in the following decades, with a large number of human fossils unearthed in Africa, more and more people began to believe that Africa is the cradle of modern people. In 196, a fossil later named homo habilis was unearthed in Tanzania, Africa. This kind of people lived 1.9 million years ago. His discoverer, British scholar Leakey, thinks that some characteristics of Homo erectus, such as thin skull, are closer to modern people than that of Homo erectus in Beijing, thus claiming that Homo erectus in Beijing is only a sideline of evolutionary extinction. This view of Niche was further supported by many western paleoanthropologists in the 197s.

In p>1987, the ancestral relationship between Homo erectus and modern people in Beijing was more seriously challenged. Cann and other three geneticists in the United States, based on the study of placenta DNA of women from different regions and races in modern times, proposed that the ancestor of modern people was a woman who lived in Africa about 2, years ago. Later, people borrowed the story about God creating man from the Christian Bible and called this woman Eve. Since then, this hypothesis has also been called the Eve hypothesis. Later studies suggested that Eve might be a group of women. According to this hypothesis, some of Eve's descendants spread out of Africa about 13, years ago and arrived in Asia and Europe, replacing the ancient people who lived in these areas, and later developed into modern people in these areas. According to this hypothesis, modern China people are descendants of immigrants from Africa 13, years ago, and these descendants have not absorbed the genetic genes of East Asian aborigines at all. That is to say, the ancient humans represented by human fossils discovered in China earlier than 13, years ago, including Homo erectus, were completely extinct, without a descendant and even a few genes passed down.

Eve hypothesis has caused an uproar in academic circles again. Whether modern people are all from Africa has become a central topic of heated debate among anthropologists all over the world for more than ten years. Just as Richard Leakey, a master of ancient anthropology, said, "The origin of modern Homo sapiens is the most hotly debated issue in anthropology at present ... It is rare for a month not to hold a meeting, or to publish a large number of books and scientific papers to debate these issues". . . . . . . . . . .
