The Uygur are the clear outlier population, doubtlessly due to their substantial Caucasoid admixture and geographical position in Central Asia, a region that was traditionally at the outskirts of Chinese civilization. Other Altaic speakers (both Mongolic and Tungusic) are also divergent, as are the Dai/Lahu people from the China/Thailand/Laos area.
Interestingly, the Tujia people from Central China seem to be the ones most like the Han overall, with Hmongic Miaozu/She more like the southern Han.
