I hope soon. As I was reading the book by Oppenheimer and his saying that some of the refugees from Sundaland went up the rivers/waterways of Asia, even into Tibet. I kept thinking of these Tocharian folks. Are Europeans from Asia?
Of course the linguists would say that they are distinct and unrelated to the Indo-European. So this gives you six distinct areas of cultural origins. Semetic Middle East, Europe, North Africa, Iran/Stepp, China and Southeast Asian basin. Each has very distinct elements very early that the others do not.
