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。

Research on Jefferson's Y has already given us one huge surprise. It has long been suspected that Jefferson's father children buy his slaves Sally Hemings. A 1998's study use the Y chromosome proved that it was almost certainly true. It showed that this white man apparently had black descendants. Now wells believes he has discovered about Jefferson that no one suspected. A discovery not about his descendants but about his ancestors, and it could take us a big step toward Adam. Wells notices that Jefferson's Y chromosome mutations don't look european. So where did Jefferson's ancestors come from?

To find out the turth, Wells needs another DNA sample. The Tralle Leese dwell on virginia. One of the closest living relatives of founding father lives in freze Virginia.

W: Now do you have any any sense of europe ancestors during the /

T:Thomas Jefferson.

/ Jefferson shares the founding father's last name. he also inherited his Y chromosome.

W:It's not gonna hurt, and you rub on your inside your cheek, really scrape away up and down.

Everything about Jefferson points that he has been a european. Geneologist has traced his ancestors back to the mediaeval France and Britain. But the test reveal something you may never have imagined. Jefferson's Y chromosome links not the europe but to the middle east what is now Lebanon and Syria. This is the best guess. But direct ancestors would lived on a land that no long exists called Furnitia. The Bible calls it Cana. Jefferson may look european. But his Y chromosome tells a different story. It shows that what we look like may not really tell us where we come from. And it raises a question mark over the traditional image of Adam. For centuries artists has painted him like this, like an european. For many of us, this is Adam. Michelangelo's famous painting in Vatican Sistine Chapel. He looks like a beautiful Italian. He spends a lot of time on jam. The common ancestors of all man really look like this. The story of Jefferson's suggests he could look very different. But Jefferson can lead us much further back than his Furnitia ancestor. Jefferson has particular mutation that he shares with the man from many different countries.
