"When I was a boy, it was taught that they developed narrower eyes to protect their vision as they crossed the Gobi desert into China. "

The distinctiness of the Chinese are a mystery to me. However, I do know that as recent as 2,000 years ago, all the people to the north and east of the Gogi Desert were Caucasians. The Great Wall of China was built to keep out these Caucasian people with names like, Xiongnu, Saka, Yuezhi, Sogdian and many others. There are many poems lamenting the green eyes of the Han Emperors.
