2,000 Year Old Mongolian Tomb Yields 70 y.o. Westerner

One of the reasons DNA studies are so interesting is that they expose information that wouldn't immediately be available through other means.

And even when physiological remains do speak clearly, it is not with the same sort of accuracy.

In this article from DiscoveryNews for example, it's clear that the skeletal remains that have been unearthed in a 2,000 year old cemetery are of an important older man somewhere in the range of 60 -70 years of age. But DNA analysis shows that he had western genes.

This long-dead individual possessed a set of genetic mutations on his Y chromosome, which is inherited from paternal ancestors, that commonly appears today among male speakers of Indo-European languages in eastern Europe, central Asia and northern India, Kim's team reports in an upcoming American Journal of Physical Anthropology.

... The Duurlig Nars man's genetic signature supports the idea that Indo-European migrations to northeastern Asia started before 2,000 years ago. This notion is plausible, but not confirmed, says geneticist Peter Underhill of Stanford University. Further investigations of Y chromosome mutation frequencies in modern populations will allow for a more precise tracing of the Duurlig Nars man's geographic roots, Underhill predicts.
