    • n cephalization In biology, a term first used by J. D. Dana to denote a tendency in the development of animals to localization of important parts in the neighborhood of the head, as by the transfer of locomotive members or limbs to or near to the head (in decapod crustaceans, for example), or the concentration of plastic force in parts composing the head, or subserving cephalic functions. It is accomplished in various ways: by the transfer of members from the locomotive to the cephalic series; by participation of anterior locomotive organs in cephalic functions; by increased abbreviation, condensation, and perfection of structure anteriorly, with the opposite qualifications posteriorly; or (in man alone) by the uprising of the cephalic end, till at last the body becomes vertical.
    • n cephalization A supposed tendency to a gradual increase in the size of the brain correlative with cultural development.
