Summary:
CD gives his definition of "highness" and "lowness" as "morphological differentiation" from a common embryo or archetype. JDH’s view, with which CD agrees when it can be applied, is the same as Milne-Edwards’, i.e., the physiological division of labour. There is little agreement among zoologists and CD admits his own lack of clarity.
