Of Placozoa and Porifera, which branched off first? (Conversely: which are closer cousins to us?)
I've heard both suggested as our most distant cousins with bodies, so was wondering which ordering is currently considered most likely. Of suggestions that Placozoa branched off later, I've heard some saying that the branching was even post-Cnidaria/Ctenophora. This seems very unlikely: is it?
