Apparently, the fastest genetic change happened amongst Tibetans. The genes of Tibetans have evolved quicker than other humans in order to adapt to life at a high altitude on the Himalayan plateau; ‘mountain natives altered their genetic make-up in less than 3,000 years.’
Many Tibetans live today as refugees all over the world but especially in countries such as India, Nepal, Britain, America and, Switzerland. Their love of Buddhism travels with them.
