Re: The Tokharians

Outliers are outliers. If you can't explain them, you just live with
them -- while making full use of their testimony for IE studies.

Look at Romany, an Indic language found in Europe, clear to Ireland;
imagine how we would be scratching our heads if the Indo-Iranian
branch were a tiny, and now otherwise extinct branch of IE. We are
similarly at a loss to explain how Armenian got to Armenia.
