From: Four myriapod relatives – but who are sisters? No end to debates on relationships among the four major myriapod subgroups

Inferred myriapod phylogenetic relationships tested with the Approximate unbiased (AU) test. a best Maximum-Likelihood tree inferred with IQ-TREE derived from our STRICTaa dataset (59 taxa, alignment length: 95,797 amino acid positions, 292 gene partitions). This tree was also supported by various other datasets in our study. Statistical support was derived from 100 non-parametric bootstrap replicates. The tree was rooted with Onychophora. Maximal statistical support is indicated with a black dot, support is furthermore displayed in numbers (%) when not maximal. b Results of the approximate unbiased (AU) test on the STRICT data set on amino acid level. Displayed in blue are trees that can be derived from quartet topology A, displayed in red are trees that can be derived from quartet topology B (Fig. 1). Hypothesis A1 (identical with our best ML tree) and A2 were not rejected, all other trees were significantly rejected (p < 0.05). $: Note that we had two variants of Hypothesis B1 that differed by the placement of Scolopendromorpha, Lithobiomorpha and Geophilomorpha within centipedes
