They introduced the wheel, horses and saddles and certain metals like bronze and iron, and maybe some other new technology to the Chinese as well. Go watch the PBS documentary I posted. Even the experts, the professional archaeologists believe that now. This is no far fetched made up story man. :rolleyes: The White-Aryan Tocharians or whatever you want to call them were trading with the Chinese. This is how they introduced these new technologies apparantly. By the way, the Shang Dynasty didn't begin until 1600BC. These White-Aryans were in Xinjiang from at least as early as 1800BC. What exactly is it that defies logic again?
