Table 2.
Table gives an overview on all Maximum Likelihood (pre-) analyses and the resulting molluscan hypotheses; taxon sets aa-1 – aa-11 are based on amino acis data, taxon sets nuc-1 – nuc-11 are based on nucleotide datasets; main analyses based on aa-1 and aa-2 were additionally analyzed with Phylobayes which is indicated in the first column; Numbers are bootstrap support values of the corresponding hypothesis that appeared in that analysis, numbers followed by “pp” are posterior probabilities of the Phylobayes analysis; “-“means that the hypothesis did not appear in that analysis
