Phylogenomic analyses have revealed several important metazoan clades, such as the Ecdysozoa and the Lophotrochozoa. However, the phylogenetic positions of a few taxa, such as ctenophores, chaetognaths, acoelomorphs, and Xenoturbella, remain contentious. Thus, the findings of qualitative markers or "rare genomic changes" seem ideal to independently test previous phylogenetic hypotheses. We here describe a rare genomic change, the presence of the gene UDP-GlcNAc 2-epimerase/N-acetylmannosamine ki ...[more]
