Likelihood AU Tests of Alternative Tree Topologies.

A, B) Comparison between topology A (best tree, corresponding to the Figure 1) and the alternative topology B (corresponding to the best tree when Rhizaria are forced not to be monophyletic with S and A, Figure S3). C, D, E) Comparisons between topology C (best tree) and the alternative topologies D and E. Abbreviations are as follows: A = alveolates; S = stramenopiles; R = Rhizaria Underlined number corresponds to the significant P value of the rejected topology. aApproximate Unbiased Test. bLog likelihood difference.
