  1. Molecular evidence of anteroposterior patterning in adult …

    • The origin of the pentaradial body plan of echinoderms from a bilateral ancestor is one of the most enduring zoological puzzles1,2. Because echinoderms are defined by morphological novelty, even the most basi… 展开

    RNA tomography in adult P. miniata

    The manifestation of pentaradial symmetry in asteroids is simpler than in other echinoderm classes because it follows a planar organization with the rays extending around the oral–… 展开

    Evolution of axial properties in echinoderms

    The organizational modifications to the ancestral bilateral deuterostome body plan during early echinoderm evolution are so profound that even basic axial comparisons with other deuter… 展开
