Phylogeny of 11 metazoan genomes reconstructed by MGR. The gene order data is taken from the MGA Source Guide compiled by Jeffrey L. Boore. The genomes come from 6 major metazoan groupings: nematodes (NEM), annelids (ANN), mollusks (MOL), arthropods (ART), echinoderms (ECH), and chordates (CHO). Numbers show the number of reversals.
