South india has always been dark skinned people. other people from the west didn't manage to conquer them, so fairer skin complexions didn't get introduced there. North india, pakistan, afghanistan went through alot of invasions and immigrations etc etc...so their skin complexion today is fairer. Indian valley and harrappa etc were all dark skinned poeple. Fair skin was introduced by europeans and middle-easterns by alexander the great etc...

Recent Findings in Archaeogenetics and Aryan Migration Theory
Your entire "proof" (you said it's proven to be a myth) against this theory is based only on religious reasons...
the first image you posted only confirms what I said that southern India Dravidrians and the rest of the Indian subcontinent have been culturally, linguistically and physiologically distinct from each other since prehistoric times, and in no way confirms any Aryan migration at any time, and there is no historical record of the same to support any such claim, apart from the theories propagated by the British in the 19th century, as they couldn't digest the fact that there were advanced civilisations other than their own.. Aryan migration theory is just that, a theory, which has found no archeological, linguistic or DNA related proof till now in any definitive context..
the second article you posted, seems to be selective in it's findings in trying to prove Aryan migration, the same selective bias they are accusing the Hinduvta groups of subscribing to..
Aryan migration, the one you seem to wrongly attribute to Alexander due to some weird and unnatural fixation and fascination you have for him, in whatever shape or form if any would have occurred long before harappan civilization, and the origin of harappan civilization, well no one knows that..
all people in Indian subcontinent today, are an amalgamation of Indus valley and dravidrian civilisations, else you wouldn't be able to explain fair skinned south Indians or dark skinned Pakistanis..
I don't believe in religious discrimination along Hinduism Islam lines, neither the discrimination on the lines of skin color.. these are recent constructs made by and for ignorant and illiterate people..
