English: Figure 2. Maximum Likelihood Phylogenetic Tree of Metazoan Relationships Using the Concatenated Data Matrix
Node support is based on the best ML tree filtered through 1,000 rapid bootstrap replicates. Only support values below 100% are shown. Bayesian inference supported strongly (posterior probability = 1.0) all nodes with the exception of monophyly of Cnidaria. The maximum a posteriori and the Bayesian 50% majority-rule consensus trees disagreed with the best ML tree in supporting a Ctenophora–Anthozoa clade with posterior probability of 0.98. Please note that “Coelenterata” is not a taxonomic unit, but rather it is a traditional grouping for reasons of convenience. The alpha shape parameters of the Gamma distribution were 0.507454 and 0.651659 for the nucleotide and amino acid partitions, respectively. Log-likelihood = −261429.821426.
