In the book, The Tarim Mummies, Han Kangxin describes the people of Qawrighul as robust proto-Europeans. I don't know what he means by 'robust.' Anyone?
Does proto mean that they eventually became Europeans?
I was would contend that 'robust' would refer to the body type and structure of the Qawrighul, I dunnno if modern day 'Russians' would be considered European.
I see your going back some years talking about Europeans in China, don't forget the Romans. Though, they are way after your time frame.

"Does proto mean that they eventually became Europeans?"
I took it to mean a precursor group of the people we know as European, but not these people specifically, who were somehow sidetracked into modern day China.

When the physical evidence of the various desicated corpses, cranial measurements, tatoos, is combined with their clothing, the only conclusion is that they were Celts. The scientrific problem is that we have no such complete physical remains from ancient Celtic culture to compare in Europe.
