Fig. 8From: Improved mitochondrial amino acid substitution models for metazoan evolutionary studiesWe used the approximately unbiased SH test to examine tree topologies on metazoan, vertebrate and invertebrate testing datasets. For each testing alignment D, we determined its best-fit model M b . We fixed tree topologies, but reoptimised other parameters (i.e., branch lengths, parameters of rate heterogeneity model) under the best-fit model M b . Then we used the CONSEL program to assess the confidence levels for every tree topologiesBack to article page
