Evolution & Systematics

As technology advances the ability to correctly distinguish species and align them into systematics increases. We are now able to use genetic techniques combined with paleontological and biological evidence. The phylogeny is consistently changing as new evidence becomes available. The phylogenetic tree below is a current accepted version of the evolution of Echinaster sp. from the monotypic Spinulosida (Knott & Wray 2000; Mah & Blake 2012). Echinasteridae contain a large number of species which includes the genus Echinaster, 27 species, and Henricia, 91 species (Mah & Blake 2012).
