WebCtenophores were removed from the phylum Cnidaria and placed in a new phylum called Ctenophora (pronounced ti-NOF-or-uh). Although both ctenophores and cnidarians have similar bodies with thin tissue layers enclosing a middle layer of jellylike material, scientists now group them separately. WebMay 1, 2006 · It is suggested that the SOX played an important role in the elaboration of the unique ctenophore body plan during evolution, through multiple gene co-option, with compatible involvement of SOX proteins in controlling aspects of stem cell maintenance, cellular differentiation and specification. 50 Origins of neurogenesis, a cnidarian view. philip wall greensboro nc
