Please help Explain the cultural changes the Aryans brought to the Mohenjo-Daro/Harappa and Dravidian people who lived in the Ancient India

I think any direct relationship between the Indus Valley and the deep Dravidian south is unlikely because of the vast gap in space and time. Something like 2,000 years and 2,000 miles. But linguistically, if the Indus script is deciphered, we may hopefully find that the proto-Dravidian roots of the Harappa language and South Indian Dravidian languages are similar.

I don't know lots about history but I hope this helps you :)
