A topic that stirs up controversy in India is the development of Indo-Aryan languages, and specifically the idea that speakers of an early form of Sanskrit arrived in India between 2000 and 1500 BCE. While the linguistic argument is probably the strongest for the theory of an Indo-Aryan migration into South Asia, genetic evidence gathered so far supports it. In this video, other theories like the Aryan Invasion Theory and the Out of India Theory will be examined, along with the claims of Abhijit Chavda concerning the genetic evidence for or against migration of this language group into India.
