Why do some people say that China people originated in Africa?

According to the theory of African origin, modern people from all over the world (including China people) originated in Africa about 1, to 2, years ago, then went out of Africa and moved to all parts of the world to become the ancestors of modern people, while Homo erectus, who originally lived in all parts of the world, made no contribution to the local origin of modern people.

Chinese scientists cooperated with many scientists from the United States, Britain, Australia and other countries, and through the comparative analysis of Y chromosomes of 88 population samples all over East Asia, Southeast Asia, Oceania and other places, it was once again proved that Asian humans originated in Africa.

It is specifically pointed out that Southeast Asia is the main "post station" for human migration after leaving Africa. Some Africans migrated from Southeast Asia to China and crossed the Yangtze River into North China and Northeast Asia, becoming the ancestors of modern China people.

Recently, the theory that modern humans evolved from primitive people in Africa and gradually moved to the world has been widely valued by scientists all over the world. On Wednesday, a new research report sublimated this theory from different ethnographic and geographical perspectives.

Swedish scientists took blood samples from 53 participants and analyzed the mitochondrial DNA in their cells. The results show that the tree of human evolution is indeed rooted in the African continent. Mitochondrial DNA in human cells is a kind of genetic material, which means that the mitochondrial DNA in the cells of mothers and their children is the same.

Ulf Gyllensten, a biologist and geneticist at Uppsala University in Sweden, said in a telephone interview: "This study is the first time to analyze the birthplace of human evolution by studying the genome. We have used a large number of human cell analysis results, and there is sufficient evidence to prove that human beings are indeed from Africa.
