The first systematic investigation of an annelid genome has revealed that the genes of the marine worm Platynereis dumerilii are more closely related to those of vertebrates than to those of insects or nematodes. For hundreds of millions of years vertebrates have preserved exon-intron structures descended from their last common ancestor with the annelids.
