Who is the main fairy of mankind?

According to British and Russian media reports on June 5438+00, scientists from Stanford University and Russian Science Society have finally reached a surprising conclusion through years of joint research on the origin of modern human beings and human genes: about 70,000 years ago, the ancestors of human beings on the earth were on the verge of extinction. When the population was the smallest, there were only more than 2,000 people on the earth, all of whom were in Africa. Scientists claim that at present, more than 6 billion people on the earth are actually bred by these more than 2,000 human ancestors. The research results have been published in the latest issue of the American scientific magazine Human Genes. It is reported that scientists from Stanford University and Russian Academy of Sciences analyzed and compared thousands of human DNA data collected from 52 different regions around the world. After years of joint research, they finally reached the latest conclusion. New research confirms the theory that modern human ancestors "walked out of Africa". About 70 thousand years ago, human ancestors first set out from Africa and migrated to all parts of the world. What is particularly surprising is that scientists say that at that time, for various reasons, there were only more than 2,000 people left in the world, all of whom were in Africa. In other words, all modern humans-more than 6 billion people on earth-are made up of these more than 2,000 "African ancestors". Genetic differences among 6 billion people
