I haven't had a chance to go through all of this thread but I like linguistics! I am wondering, after a quick search, the suggestion is that the only surviving Paleo Balkan languages are Greek and Albanian. But not Macedonian, which I assume should be in the Balto-Slavic group?

So, the question is whether the ancestors of all these languages (modern Greek, Albanian and Macedonian) split on their own from Proto Indo european and thus, share a common ancestor.
