A list of the molecular studies used in the present communication, including data set sizes and phylogenetically informative characters. The three letter code in the “Study” column is used throughout the article to refer to these studies. Ry prefix Ryan et al. 2013; RyG Genomic, RyE EST, Si prefix Simion et al. 2017; Wh prefix Whelan et al. 2015; Ch prefix Chang et al. 2015. # Taxa “Full”, # All Ch “full”, # PI Ch represent the number of taxa in the original analysis and our “full” analyses, the total number of characters in the original analysis across the entire tree, and number of Phylogenetically Informative (PI) characters for the SOM node, respectively. SOM sister of all other Metazoa; PO Porifera inferred as the SOM; CT Ctenophora inferred as the SOM. Par “unweighted” parsimony, par6 and par11 refer to our parsimony analyses with and 11; ML maximum likelihood under WAG model, ML6 and ML11 refer to our likelihood analyses with and 11. Original refers to the results reported in the original publications for “full” taxon representation.
