    Untrue. Tibetan class system evolved from 4,000 years ago when the Chinese and Qiang ethnics people (Y-Chromosome O3 type) started to migrate to the Tibet plateau and debased the dark skinned aboriginals (Y-Chromosome D type) to the slaves. Daila Lama XIV's ancestors came to Tibet about 1400 years ago.
