I'm a mammalian neurobiologist, so it's away from my specialty, but I had the idea that current evidence considered comb jellies at the base of metazoan phylogeny, and viewed sponges as a later development (with secondary dedifferentiation)?
I believe the comb jellies have morphologically-identifiable synapses.
