In addition, an understanding of the arrangement of the primary skeletal structures during the early post-metamorphic stages of Asteroidea allows identification of the true homologies and ontogenetic patterns inferred from evolutionary models (the Ocular Plate Rule and the Madreporite Mode Appearance) (Mooi and David, 2000; Gale, 2011).
