Summary of rhizarian genetic and morphological evolution mapped on the phylogeny, combining results from Bayesian and ML analyses (i.e., fig.1 and supplementary fig. S3, Supplementary Material online). The basic branching pattern is presented as inferred by ML, since this enabled the use of Evolutionary Placement Algorithm (EPA) to place taxa with large portions of missing data (Berger et al. 2011). Branches in grey are the most likely placement of taxa from EPA with numbers showing the expected likelihood weights for the placement. The placement of Sticholonche zanclea, varied between ML and Bayesian inferences; here shown as sister to Retaria as inferred with the most favoured CATGTR Bayesian inference (fig. 1). Rhizaria is shown as sister to Stramenopiles and Alveolates, as in the Bayesian analysis. Taxa in bold are sequenced for this study. Arrows mark important morphological and genetic innovations. Thick branches are highly supported with bootstrap support >85% and posterior probability >0.9.
