> I'm no geneticist but I wonder if such statements have any scientific value or even meaning. There's no basis for that usage. The writer just used those terms to catch the attention of people who are intrigued by the largely fictional concept of "pure-blood". At most, they might have a high concentration of particular traits due to marrying only among themselves for a long time. The ancestry that the article itself purports for the tribe - moving from Central to South Asia via the Indus Valley - would mean they intersected with several different populations along that route. That route is through the crossroads of Asia, so it's very unlikely that they are "pure-blooded" in the way that, for example, the Sentinelese Islanders are - separated from any other population for 10s of thousands of years. Despite the Brokpa's current isolation, they probably share some of their genetics with nearby South and Central Asian populations, but the article provides no citations about their genetics, despite it's casual claims. This article [1] suggests that nothing is known today about their genetics at all. Curiously, it does say they are traditionally vegan. I'm not sure that even the Sentinelese themselves are "pure-blooded" in any sense of the word, but rather they just had an earlier branching point from other human populations than most, with no contact since then.
