How did Indians look like before the invasion of Aryans?

India is like acontinent which had 3 races before migration/invasion of steppe people (some consider them aryan, some consider native Indus people as aryan and steppe as older wave of sakas) So before migration India had mongoloid race in east, dravidoid in south, Iran neolithic in north west. With migration of steppe the 4th race entered into India. All three races are sub-races of caucasoid race and dravidian considered to be aboriginal population of India. Now take a look at the Steppe, the reconstructed picture in right represent man from yamnaya civilization(which was early middle bronze age steppe civilization), man in left is professor niranjan from Palwal who is JAT. Again we can see similarity between steppe reconstructed face and JAT man since jats have high steppe ancestry. Eyes, nose, lips, forehead, lips,etc all are similar in both picture.
