Results Echinodermata. Trees summarising the results of the tree reconstructions on Echinodermata. (A) Tree by the GTR and the RNA6A model setups, showing monophyletic Asterozoa and Echinozoa. Bootstrap (BS) values taken from the GTR model based tree reconstruction. (B) Results of all other mixed RNA/DNA model setups. Dotted line indicates alternative sistergroup relationship of Holothuroidea and Echinoidea. BS values taken from the RNA7A model based analyses.
