How did the Indoaryans manage to maintain an oral tradition of such quality that their culture retained more cultural elements (eg names of deities) … - Nikos Kazanas

M. Witzel attacked several scholars who since the early 1990s manifested support for the Indian Indigenous Origin (IIO hereafter); amid various criticisms he used the term “revisionists”, ignoring obviously that in the early 19th century many European scholars took India, on the strength of Sanskrit, to be the original homeland... The term “revisonist” is therefore inapplicable. Witzel ignores also that Copernicus, Kepler and Galileo were ‘revisionists’ in rejecting the geocentric system...

Sanskrit appears to have lost far fewer items and preserves much greater organic coherence than the other branches. This supports the general idea that Sanskrit is much closer to Proto-Indo-European and that, since this could only happen in sedentary conditions, the Indoaryan speakers of Sanskrit did not move (much) from the original homeland.

In summing up his extended survey of linguistic evidence Witzel tells us that the mode of the IA entry is "archaeologically still little traced"; it is, he states, securely traced in the texts (horses, chariots, religion etc) and from linguistics and possibly from future studies of the male Y chromosome (2001: 55-56). Here we have an attempt at falsification ("little" when in fact it is none) and wishful thinking. Neither horses and chariots nor linguistic phenomena, such as Witzel provides, prove any entry. They are interpretations of facts by a mind already colored by the AIT.
