“Prakrit” is origin of modern language in India, and surrounding, Indo-Aryan, the Dravidian and the Munda languages.
In recent years studies have been made to correlate genetic background of populations with languages.
These studies have had some success in describing the spread of languages. It is significant that on many counts the vast majority of the Indian population, in North as well as South India, is classed as a single group.
The attested migrations of the Indo-Iranians into Europe explains the presence of several Dravidian features in the European languages.
