Y chromosome can explain the origin of human beings.
Now, Spencer Wells, a geneticist of the National Geographic Society, has finally found Adam Science, a human ancestor who was born in Africa about 60,000 years ago, by using DNA technology. Today, his genes have spread to everyone on the earth.
Y chromosome can explain the origin of all human beings on earth. However, if we want to find the ancestors of the same ancestry, the key is to find the "super ancestors", that is, people who have left genetic marks on many people. They are like branches, countless branches, which will eventually come down to one person. Geneticists can trace the tree step by step until they find the ultimate apex-scientific Adam.
Studies have shown that the Y chromosome can trace our lives back hundreds of years. But if we want to find the scientific Adam, we must start from scratch and look for the ancestors of hundreds of millions of people, not millions.
Family history is difficult to query, and there is only one way to clear the fog, that is to analyze the Y chromosomes of those who still live in their ancestral homes. In order to describe our genealogy more clearly, Wells cooperated with the National Geographic Society and IBM to start a project called "Gene Mapping". After the plan is completed, Wells can find out the source of everyone.
Fossil evidence shows that humans may have originated in three regions: Asia, the Middle East and Africa. Wells hopes to find the intersection of human beings in Asia, the Middle East and Africa. By studying the ancient trade routes, he found a possible place, which is Patai Island off the coast of Kenya. For centuries, businessmen from all over the world have gathered here. They come from Europe, the Middle East and even China. History has created a great fusion of genes.
Scientific Adam probably exists.
DNA analysis shows that people on Patai Island come from all over the world. These samples also illustrate a key situation. They all point to a new super ancestor. Although their Y chromosomes come from all over the world, almost all of them have the same feature, a special variation called M 168 by scientists. In fact, almost 3 billion people on earth have this mutation. This means that they all have a common ancestor. Indeed, there was once a man who gave life to all people today. He is our ultimate super ancestor, and he is Adam of science. Wells believes that the pattern of Y chromosome in Africa shows that the birthplace of scientific Adam should be near the Rift Valley in East Africa. Gene technology can infer the age when scientific Adam lived. Wells thinks he was born about 60000 years ago. There is no doubt that he is neither a prehistoric homo erectus nor an ape. He is a modern man.
