History of Pashtuns series

Re: History of Pashtuns series

I have not reached to any conclusion but i am interested in any scientific and anthropological investigations about origin of pashtuns. The problem is Pashtuns have not recorded their history. We have some clues about them from greek or persian sources but nothing can be said definite about them. One thing is clear, they are east indo-iranian people and their langauge is derived from avestan , it seems layers of scathyians/sakas, bactarians, hepthalites, khalaj , turks etc were added to them in the course of history.
