The annelids, or ringed worms, comprise one of the largest and most diverse animal phyla, and are found everywhere from garden soil to the deep sea. Their precise phylogeny has always been sketchy, but now, a new phylogenomic analysis unravels annelid evolution. Notable features include a division of most annelids into the Errantia and Sedentaria — a restitution for two groups based on classical morphology — showing how many details of anatomy and life history bear on the evolution of this important animal group.
