From: Hox gene expression during development of the phoronid Phoronopsis harmeri
Bayesian phylogeny under JTT + I + G substitution model of the amino acid sequences of spiralian Hox genes homeodomains, including phoronid sequences. Genes from Ph. harmeri are marked in red. Posterior probability values are shown for important clades. Full species names and sequences accession number are provided in Additional file 1: Table S1
