quotes:
"Most linguistic arguments given here by Prof Hock and Prof Michael
Witzel cause NO SERIOUS PROBLEM to the theory that the IE family
originated in India (emphasis added)."
"I (Koenraad Elst) leave it to the more technically inclined linguists
to look into this more closely. For now I must confess that after
reading Prof Hock's presentation, the linguistic problem which I have
always considered the most damadging to the Indocentric hypothesis,
doesn't look all that threatening anymore. I do not believe that the
isoglasses discussed by him necessitate the near identity of the
geogrphical distribution of the PIE dialects with the geographical
distribution of their present day daughter languages, which near
identity would indeed be hard to reconcile with an out of India
hypothesis.
