Iranians were mostly classic Aryans...from the Big Split some call it where some Caucazoids went South and East and some went North and West.
I'm way out there now...hanging from El Capitan with one hand and no rosin left.
Some actually say that the only true Aryans are from India and Iran. By the way, did you watch that PBS show on Gypsies in Europe...fascinating stuff. They can actually trace them all the way back to Rajisthan, India.
Actually,you're doing quite well. :-)
