The idea of the "Aryan race", however, as a strictly ethnic intepretation of the word that extended to Europeans, arose when linguists identified the Avestan and Sanskrit language as the oldest known relatives of all the major European languages, including Latin, Greek, the Germanic, Celtic and Slavic languages. They argued that all of these languages originated from a common root - spoken by an ancient people who must have been the ancestors of all the European, Iranian, and North Indian peoples.
These hypothetical ancestors were at first given the name Aryans by linguists, despite the fact that the word was never attested in any European sources. From this point the term "Aryan" came to mean something similar to "white European" * although excluding the Jewish
and Arab peoples and including the inhabitants of Persia and North India. In modern times, however, the word is not used by linguists or ethnologists to describe this group, who now prefer the more neutral Indo-European. The only remaining common use of the word in linguistics is in the name of the Indo-Aryan language sub-family.
Persians According to Wikepedia:
"It is one of the ironies of history that Aryan, a word nowadays referring to the blond-haired, blue-eyed physical ideal of Nazi Germany, originally referred to a people who looked vastly different. Its history starts with the ancient Indo-Iranians, Indo-European peoples who inhabited parts of what are now Iran, Afghanistan, and India. contemporary anthropologists who believe in the existence of an ancient Aryan race generally have the opinion that its closest descendants today are the Persians, not the Germans; that is, if Aryans existed,they were white after the manner of imperial-era, pre-Muslim Persians,and possibly the Circassians and southern Slavs, but certainly not the Nordic Germans and English.
Modern research considers "Aryan" merely in connection with the Iranian and its preliminary stages. "Indo-Aryans" are seen as precursors of e.g. the Persians. "Genetic purity" was banished to the realms of myth. Yiddish is as much an Indo-European language as any other Germanic
dialect and the language of the Roman gypsies is much closer to "Aryan" than any of the Northern European languages.
Comments on Wikepedia: This is how Wikepedia defines Persian Aryans. Pre-Moslem Persians means that Persians might have been white, but now they are mixed with Arabs and they are not white anymore. Also note that Wikepedia equates Persians with Gypsies and Jews speaking Yidish (no offense to Jews or Gypsies but that is a little bit oversimplification). And Persians look like Turkish Circassians similar to the picture with hooked noses. For a discussion of hooked noses see here. Also stating that Aryan race is a myth in Iran. Also it is unclear how they mix up Anglo-Saxon British with Germans and call English Nordic.
