Tibetans: Why are they so Genetically Distinct?

Who exactly are the Tibetans, and why are they so genetically distinct? Living on the world's highest elevated plateau, the Tibetans have become uniquely suited and adapted to this somewhat anomalous landscape, distinct from all the surrounding people groups.

There are many reasons behind this evolutionary path, some of which aren't too surprising, while some are quite bizarre to say the least. In today's video we'll be going over the genetics, language, culture and history of the Tibetans, other Tibetic peoples and the whole of the Sino-Tibetan family. Thanks for watching!
