Re: Good New Book

The Lophophorata have long been considered closely related to deuterostomes, and the trochozoans long regarded as related to ecdysozoans.
I have no objection to recognizing Lophotrochozoa as a paraphyletic group giving rise to the other two (if one finds it useful), but treating it as a holophyletic clade is definitely a cladistic no-no.
What synapomorphies do the Hox genes of Lophotrochozoa display that indicates that it is a clade, or any other lophotrochozoan synapomorphies for that matter?
Cheers, Ken

I'm still curious to find out just which lophotrochozoans you consider closer
to deuterostomes or ecdysozoans (or both together?) than to other
