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。

So how many people in Mongolia really believe that they are related to Genghis Khan. Every single person...

Every single person. (million people living)

It seems purposed as if everyone in the America believe they are descendants from George Washington. But if there's any truth to their claim, these men will link back to a common ancestor lived generations ago. The first step on our journey back toward Adam.

So you guys have interest in finding out if you could be related to Genghis Khan himself?

Yeah, let's go.

O.K.

And then I'll pass...

Tapping the power of DNA, start with a basic tool.

By the way, it's just a clinical glorified toothbrush. Pull it out of the container. Just like that...

Just a few cheeks outs , and Wales can unlock secrets from our genetic past.

With the simple swab, Wales hopes to trace these man all the way back to a famous warrior lived 8 hundred years ago, and thousands of miles away.

Genghis Khan is one of the greatest historical figures of all time. Eight centuries ago, he ruled one of the largest empires the world has ever seen.

What are the chances that a couple of guys in a San Francisco bar could be related to such a extraordinary man? Machines analyse the Mongolian's DNA, looking for traces on the Y chromosome that could link them to Genghis Khan.

The acts against finding the connection seem astronomical.

But Wales has some surprising news.

I've go the results.

He's found the evidence that two of these man are related to Genghis Khan.

These are your results. Serantorsh, dumped out.

And Bator to none
What makes Wales think that these men link back to Genghis Khan himself? He's never met them before. He doesn't have their family trees. And he doesnt' have Genghis Khan's DNA. But Wales believes the Y chromosome can confirm the link.

Most of the time, the Y chromosome is passed unchanged from father to son like a last name. But some times little differences could have been. Like the spelling of a family name changing over time. Every so often, a harmless mutation appears on one man's Y
chromosome. All his sons inherit that mutation, and all their sons. It marks all descendants like a brand.
