I know little about language, so I would like to preface that this question may appear disjointed. I have been listening to some wonderful Georgian folk music and have been trying to relate it to any other language that I have heard, but it sounds so unique. I almost thought it sounded a little like Turkish. I found that it belongs to the Kartvelian language group which evolved from proto-kartvelian.
Can someone tell me where Proto-Kartvelian evolved from? I have looked up multiple images of the language tree and have not found it on any of them (I've looked at probably a dozen).
Where does this language fit in? It's not a subfamily or Indo-Iranian or Anatolian.
It's clearly not germanic, Italic, or Slavic (though I do hear some similarities to Slavic).
