The point being made though was that the languages are well shown to be genuinely related through a common ancestral language from which they both deviated, just as have most languages in Europe and parts of the Near East. The connection is tangible and quite real, not something just based on some few similarities.
Maybe not news in the sense that it’s a new development (though the title implies it is a deterioration), but still very much worthy of reporting. Just because something is typical doesn’t mean it is unremarkable.
