Hey, you could get you picture on the cover of Archaeology Magazine if you could connect Kennewick Man's DNA to the DNA of the Tocharian mummies of the Tarim Basin and Gansu, China. These were all Caucasians there until the Han skeletons started showing up around 100-200BC.
There are many poems in Chinese lamenting the green eyes of the Han emperors. Their 'magic-men' were noted for having red hair too.
Asians were probably in China first.
