Han Pashtuns are Central Asian Mongols and this is why they have bulging round heads like a Mongoloid.
If you are white and have blue eyes than one of Alexander’s men hung around like many Greeks who remained in Pakistan.
If you are a Pashtun you are not white or South Asian but a Mongoloid with a roundish head and flared nostrils like Genghis Khan.
Probably not the case, although maybe this is a common story.
Pashtuns are generally considered to be Eastern Iranians. A few tribes may have Arab or even Mongol origins. And some may be related to Alexander’s group. One of the groups making them up was the Hephthalites or White Huns. The White-looking people are probably from the White Huns, who had fair complexions. Maybe originally a Tocharian group. The name Han of the Pashtun Hans is related to the word Hun.
But the Pashtuns are generally not thought to be Mongols. Anyway they showed up there 3,500 YBP which correlates with the arrival of the Indo-European Aryans in the region. They also speak an IE Eastern Iranian language.
