I'm a cladist, and I don't. I substantially agree with what you say about
speciation in this post (in fact I teach it to my students), but I don't
think it has anything to do with the broader question of recognizing
paraphyletic groups, especially since the bulk of them show no evidence of
being the leftovers of a speciation event.
