Figure 2. Maximum-likelihood tree for 95 in Molecular phylogeny of the Forcipulatacea (Asteroidea: Echinodermata): systematics and biogeography

Figure 2. Maximum-likelihood tree for 95 forcipulate taxa and nine velatidan taxa, rooted on 111 taxa belonging to the Valvatida, Paxillosida, and Notomyotida (these taxa have been omitted for clarity), and based on 261 bp of sequence data for the 12S rDNA gene and 437 bp for the 16S rDNA gene. Bootstrap support values are based on 250 pseudoreplicates and are shown as percentages when ± 50%. Named clades correspond either to traditional taxonomic groups or to geographically restricted lineages.
