Interesting! Got one more link here:

The article refers to "relic" populations on the peripheries of Asia, such as the Ainu, Hmong and some Tibetans and Andamanese. This really caught my eye, however:

A finding of particular interest is that the Andamanese do not carry another Y chromosome signature, known as Marker RPS4Y, that is common among Australian aborigines.

Now, if only this came from a reliable source instead of the New York Times! :-))
