Before we can answer questions on the origins of morphological and ecological diversity, we need a solid understanding of the phylogenetic relationships of the species of interest. Ideally, this phylogeny is backed by sufficient amounts of data and represents the diversity of the group. In this Issue, authors investigated the phylogenetic relationships of Terebelliformia, a group of mostly marine segmented worms (Annelida) that includes spaghetti worms, Pompeii worms, ice cream cone worms, and their relatives. A dataset of thousands of genetic loci sequenced for the main lineages of the group formed a well-supported backbone, which guided the analysis of smaller but taxonomically more representative datasets for 121 species. This approach provided a robust understanding into the relationships among different lineages and into the evolution of their remarkable morphological diversity. View this paper.
