Note "major". Meaning that it is *very* hard to
impossible to make classes monophyletic, but in most
other caases it is entirely possible. For example, one
might argue that Artiodactylata is a junior synonym of
Cetacea. Or, to preserve them, move taxa about.
Porifera, split in two. What happened to the
Insectivora is a case in point.
