People all over India look same or similar.Only people in southern state of tamil nadu and Srilanka are dark.But this does not mean that there were two races in India.This History of Aryans and Dravidians may not be correct.People talk of Aryan Invasion because few people are fair.If you look at caucasians they are very different from people of India.I dont
think they ever mixed with people of India.Todays population of India does not Include Aryans or Dravidians.There were few muslim Invasion but they have their own religion and culture.India is a very old civilisation.Gods vishnu,shiva and Brahma are part of our culture,they have not come from outside.
