Surprisingly complex T-box gene complement in diploblastic metazoans

-
Our analyses show unexpected complexity of the T-box gene family in the diploblastic animals, which is consistent with other investigations in these animal groups.

All These Different Creatures are Variations of the Same Theme 2008

"Because all three main clades of bilaterian animals express a let-7 RNA that is temporally regulated, but cnidarian, poriferan and all non-animal species that we analysed do not express a detectable let-7 RNA, we propose that the gene evolved after the divergence of diploblastic and bilaterian animals"

If you take a look at animal phylogeny, an important group are the diploblastic phyla, the cnidarians and ctenophores.
-
I was under the opinion that ctenophores differed from cniderians because of the presence of a third layer; perhaps not a true mesoderm but not diploblastic in the same sense that cniderians are.
