Great project. One thing that is masked by the tree view though is that there were indeed countless other languages being spoken besides Proto-Indo-European. It's just the one that gave rise to today's Indo-European languages. But back then it wasn't alone, but just one of many, some related to it and some more distant from it. Kinda similar to how it works today. It had dialects, it was in motion and change, it had earlier versions etc. etc.

Well, yeah, but that's like saying that producing a tree of pomaceous fruit hides the fact that citrus fruits exist.

(Yes, I did make an apples and oranges joke.)

		The tree appearance just makes it too inviting to imagine PIE as some pristine ur-language, the kind of original language of Babel. I'm not saying that people explicitly think these thoughts, just that it's easy to get this impression, even if it's not conscious. The fascination about the original human tongue in Eden used to be a common intellectual preoccupation. My point here is that PIE is quite a different story.
