You are correct. Populations change and intermixing occurs. Then history is rewritten. Today we can see the mouth breathers who happily swallow the Jewish revision of our history.

Iran literally means land of Aryan. We are called Caucasians because Adam's (the first white) people came out by of the Caucus Mountains after the Younger Dryas.
The indo-Aryan, Indo-European, is the white Caucasian of today. Beware anyone lying and telling you otherwise.
In India, that intermixing is why the northern and southern Indian populations are visibly different. The southern population is minus much interbreeding.
Beware the liars...
