Best tree from the Maximum Likelihood analysis (RAxML 7.00, mtREV, G+I, single gene partitions) of the reduced taxon set (30 lophotrochozoan species). Numbers beneath nodes indicate support (from left to right or up to down, respectively): (1) through RaxML bootstrapping (1000 pseudoreplicates) (2) ML analysis with Treefinder (1000 pseudoreplicates), model mtART+G+I, (3) Bayesian posterior probabilities (model mtREV+G+I). Triple asterisks indicate maximum support from all three analyses (100/100/1.0). See Table 3 for complete species names and accession numbers. Single asterisks indicate taxa with incomplete mt-genome information. Scalebar depicts substitutions per site in the best RAxML tree.
