> Miguel's pre-PIE changes look plausible to me, except in one important respect: I find a system with no high vowels typologically implausible, even as a transitional stage. Whenever /i/ and /u/ (or their long counterparts) vacate their slots in any system (as a result of lowering, diphthongisation or whatever), other vowels _immediately_ rise to fill the empty positions. It doesn't matter if you declare vocalic [i] and [u] to be allophones of /j/ and /w/. Such allophones at least (or independent high-vowel phonemes) should exist in a vowel inventory that has diphthongs like [ai] and [au]. Even a really rudimentary vertical system like Kabardian, in which there are no diphthongs and monophthongs have given up whatever colour they once had to the consonantal shell of the syllable, retains minimally a [+/- low] contrast.Thanks.

> I must say Miguel's explanation of ablaut and stress patterns looks convincing, but he does seem to me at times to stretch typological plausibility while striving for formal elegance. The evolution of "his" vocalism begins with a triangular arrangement of vowels -- so far, so good, few things could be less common -- and culminates in the geometrically perfect "classical PIE" system; however, the intermediate inventory (*a, *a:, *ai, *au, *a:i, *a:u) is embarrassingly "marked" despite its fearful symmetry.
