Not entirely random - I picked the most prominent of the prominent features highlighted on the article's photo of the skull. It's just that it's opposite to what my first guess would have been - poor nutrition / health / etc would mean less nutrients like calcium (or cause calcium to be leeched), so bones like the jaw would be smaller, not bigger. Maybe the chinless upper classes drank too much gin and tea and not enough milk.
