美国国家地理学会的遗传学家斯班瑟•威尔斯利用DNA技术经过多方的寻找,终于找到这位人类祖先———科学亚当。今天,他的基因已经遍布于地球上每个男人的身上。
With the same techniques used on Genghis Khan, Wales can link this mutation to another critical common ancestor. He’s known as M9. he lived around 40,000 years ago. Wales’s research suggests this one man could the forefather of half of all men alive. We are getting closer to Adam. But Wales knows there are some men who do not have the M9 mutation. To identify the common ancestor of all men, he must take us deeper down the tree. But where does he go next? There are clues from beyond the world of genetics. It’s evidence you can touch, evidence from bones. Before the powerful new tools of DNA, our picture of humanities' past came almost entirely from fossils. But that picture is incomplete. The oldest human fossils come from Africa, dating back millions of years. But ancient remains have been found at other sites far away. The Middle East has produced early human fossils and pre-human remains have been found in Asia. Fossil evidence points to three regions that could be the birthplace of human kind—Asia, the Middle East and Africa. Can DNA result which one give birth to scientific Adam?
Wales wants to find a place where people from all three regions are in a set. A study of historical trading rounds offers a likely candidate. Off the coast of Kenya, the tiny island of Pate. A mysterious place with clues that seem out of place in Africa. Curious ruined ones.

Monuments that might be Islamic. Tombs that look almost Chinese. Even the faces who dressed in the trigging mix. Some have the lighter skin tone of Europeans. Some could be Arabs. Others have eyes that look Asian. For centuries, traders have come here from all over the old world. From Europe, the Middle East, maybe even from China.
