Evolution of snRNA, snoRNA, and miRNA families. A the terminal branches of the phylogenetic tree we report the number of families annotated by this study. At the interior nodes the inferred number of families present is shown in black. Gain/loss events are displayed along the edges with green and red numbers, respectively. Abbreviations for species names: Prot: Protostomia, Cel: C. elegans, Bfl: B. floridae, Odi: O. dioica, Bsc: B. schlosseri, Dvex: D. vexillum, Cin: C. intestinalis, Csa: C. savignyi, Pma: P. marinus, Dre: D. rerio, Lch: L. chalumnae, Xtr: X. tropicalis and Aca: A. carolinensis
snRNAs. The snRNA families included were: 7SK, Rnase MRP, Rnase P, SRP RNA, U1, U2, U4, U5, U6, U11, U12, U4atac, U6atac, vault RNA, Y RNA and SmY.
