Maximum Likelihood Tree of (pre)GNA- genes. ML tree built with all paralogs and sequences evaluated. The tree is also included as separate file with BS values in Nexml format Additional file 2: Supplemental file 1. See Additional file 1: Table S1 for taxonomic groups. A reconciled, rooted gene tree of all evaluated (pre)GNA- genes in Holozoa is included as with reported bootstrap values of > 90% with all preGNA- genes denoted in black. The inference of gene duplications based on the gene tree and species reconciliation are in accordance with the hypotheses discussed herein. Major differences are indicated otherwise
