From an anthro stand point I would hypothesize it is because the different villages truly are physically isolated, in the mountains for many years to develop different languages.
It gives one thought as to the difficulty of fighting in such areas.
And the difficulty in the battle for the hearts and minds through some contact, news papers, FM radio, AM radio?, internet?
( The Taliban seem to have over come the language difficulty. )
Any one know of any reports?
