What is the Aryan Invasion Theory? What is the basic premise? What are the problems associated with this theory? Can there be another alternative? I try to discuss this and some other related issues with Shrikant Talageri. You can read Shrikant Talageri's work at http://talageri.blogspot.in/

You can buy his books here http://www.amazon.in/Rigveda-Avesta-Evidence-Shrikant-Talageri/dp/8177420852/ref=sr_1_1?ie=UTF8&qid=1491751110&sr=8-1&keywords=shrikant+talageri
