时差N小时 成吉思汗(下)

Researcher Tatiana Zerjal, from the University of Oxford¹ in England, and a team of geneticists took genetic² samples of over twenty-one thousand men from all over Asia.

牛津大学研究人员塔缇娜瑟加尔和一组基因学者采集了亚洲21000份基因样本，

They were looking for variations in certain genetic “markers,” or sequences of genes³ that tell you something about where people came from.

从中寻找某种基因“记号”或基因序列变化。基因序列可以识别出身。

To their astonishment⁴, they found that one out of every twelve Asian men in regions once part of the Mongol empire carry a form of the Y chromosome⁵ that can be traced to Mongolia a thousand years ago.

令人惊讶的是，他们发现曾是蒙古帝国疆域，每12个人中就有一人携带追溯到千年前的蒙古基因的Y染色体。

How did this genetic tag become so widespread?

为何这种基因“标签”流传如此之广？

Khan, they suggest.

他们认为是成吉思汗。

There is reason to believe that Khan himself, and thus his long-ruling descendants, had this particular form of Y chromosome.

研究人员猜测，有理由相信成吉思汗及长期统治的后裔都有这种特殊的Y染色体。

And though his power is long faded, the genetic empire of the conqueror⁶ is going strong–in roughly one out of every two hundred men alive today.

虽然时至今日，成吉思汗的政权早已衰败，但是成吉思汗的基因却留在人们的血液中。今天，大概每200人中可能就有一人有这种基因。
