I don't know whether you heard about the Kalash people of Pakistan.. They look distinctly different and also have various theories like being descendants of Aryans and of Alexander..
Also in this context I would suggest you all to read an absolutely amazing book called "Empires of the Indus" by Alice Alibinia. A history of all the civilizations that thrived along the Indus river banks right from Karachi to Tibet
There are three theories: Aryan Migration Theory (AMT), Aryan Invasion Theory (AIT), and Out of India Theory (OIT). All are 'theories', none have been established conclusively. Similar debate is for the definition of the Caucasian people also. As @munna219777 said, it is more linguistic these days than ethnic.
Hitlar's theory was slightly different. Something like Nordic=Aryan. And both are superior to other nations. And Jesse gave it a public burial.
