There are two issues here, recognition and understanding. Yes, no-one will
argue that many paraphyletic groups are recognisable. But my hunch is that
they are rarely (I would hate to say never) interpreted as if they are
paraphyletic, unless one is told otherwise. The structure of "folk"
taxonomies is pretty much hierarchical in the same sense as a "Linnaean"
hierarchy and in the same sense as Darwin's box-in-box classification. I
think that we are talking about nouns and adjectives and such-like things
