Hypotheses of evolutionary transitions in scalidophoran and cycloneuralian morphological characters. These hypotheses are based on the three possible relationships within the Loricifera + Nematoida + Panarthropoda clade. Sc and Cy above branches indicate morphological characters of the ‘Scalidophora’ and ‘Cycloneuralia,’ respectively; ‘ + ’ and ‘–’ indicate the presence and absence of characters; asterisks indicate well-supported nodes
