== 3500 BCE == 

 The article says Talageri places the RV at 3500 BCE. Can the book and chapter please be used as reference. Witzel can be used as reference when discussing criticism of Talageri, but when describing only Talageri's model, Talageri or a neutral source like Bryant should be cited. Especially because Witzel has also been criticized by Talageri for misrepresenting Talageri.
