Etymology has little to do with biology, other than sharing a morpheme. One's language has little to do with one's DNA. Schlegel's connection of Sanskrit arya with Greek aristos is not without its problems. It is usually regarded as being cognate with the root in the new name of Persia, Iran. Iran was chosen mainly because the Pesians wished to distance themselves from Arabs. The only folks I know of today who speak of Aryans are South Asians and white supremicists. So, not sure what this is all about, but since Freidrich Schlegel died in 1829, he must've been ouijaing from beyond the grave.

Ceci n'est pas un seing.
