The article describes Aryans ranging from Europe over India to Nepal though.
Well, that is the problem with open source encyclopedias.
Aryan people once lived in such places thousands of years ago. But they were breed out and today just mongrel races live there. The problem here is the lack of racial awareness of who produced that definition. Aryans are just really "white people", from the sun tanned Mediterranean to the milk skin Nordic, from the strong eastern European to the Auburn haired Irish and Icelander.
Ok so I guess you are taking it back that the wiki article is correct because it seems you are not agreeing anymore.
Can you explain me then if being aryan is based on genectics or language?
Because if I remember correct around year 0-1000 most Europeans were living in caves while we already had high civilization in Asia, Africa and south America?
