Hmmm. Ararat?
The map depicts the spread of language exactly like described by the author Steven Collins in his books on the lost tribes of Israel.
see for example:

It's plausible, but then we have the Hurrians (ancestors of present day Georgian peoples) who are there in the same Anatolia plains and who get conquered by the Hitties around 2500 BC.
Also, the Greece substrate (Pelagesians?) were non-indoeuropean in language yet seem to have been pushed south by indoeuropeans coming from the north.
