The draft genome of the ctenophore Pleurobrachia bachei (Pacific sea gooseberry) is presented, together with ten other ctenophore transcriptomes — these genomes have a very different neurogenic, immune and developmental gene content when compared with other animal genomes, and it is proposed that ctenophore neural systems, and possibly muscle specification, evolved independently from those in other animals.
