As I was researching on Younger Dryas and the impact on languages, I
find that the subject was cursorily covered earlier in Oct. 2000 on
the Cybalist list with contributions by, among others, Jonathan
Adams, Marc Verhaegen Piotr and John Croft.
I have collected the hypotheses and related essays at the following

I shall be grateful for further inputs on this subject.
It appears that organized agriculture terminology will hold the key
to the definitive leads for urheimat. I would like to underscore the
observations that in Bha_rata (that is India), the terms for
organized agriculture are not traceable to IE or Dravidian or Munda
but to 'Language X' (could be para-Munda?). Is the situation similar
in other Central Asian regions? How authentic is the basis for
statements often found that Munda languages are not found west of
Sindhu?
Obviously, farming would have been tough during Younger Dryas.
