Hi,
For about a certain time, i'm thinking on the point that R1a - blond hair and satem languages + plus R1b red hair and centum languages seems to have a good continuity, one of the point who escape at that theory is the Tarim Mummies than a lot of person relate to the Tocharians. I've learn couple of days ago, an article of the R1b-M269 haplogroup found in Afanasevo culture.
I can't put a link but its easily find on google.
I've also read about a long time ago, an article who talk about an ancient chinese royal delegate or monk, who relate the existence in chinese Gansu province and not in Tarim basin of red heared and green eyed barbarians. Of what i know the sample of tocharians language found in xianjang date of the middle-age.
So i'm thinking, are we really sur that tarim mummies were not just Scythians related people, because we know that city-state of east tarim basin were more sedentare iranians because the toponymy ( kashgar, .
Plus, some turkish people like turkmens and uygur seems to have a little of R1b and of what i know of reconstructed tocharians language like some baltic language are few more grammatical case coexistence with agglutinate uralic language who can be explain that tocharian are an pigdin of indo-european dialect and proto-turco-mongol agglutinate dialect or than tocharian can be a royal vehicular language ( langue de préstige ) while autochtons turkish people continues to talk their native language.
Give me your returns. Thank You and pleasure.
