DORSAL-VENTRAL INVERSION HYPOTHESIS. “This reversal in the relative location of the CNS led Geoffroy St-Hilaire to propose in 1822 that the dorsal-ventral axes of vertebrates and arthropods are homologous but reversed in their typical orientation to the substratum. In other words, dorsal in vertebrates corresponds to ventral in arthropods.”
