The geological longevity of Lingula , depicted, suggests that the lightly mineralized carbonate‐substituted fluorapatite (FAP) shell has remained well‐adapted to evolutionary pressures. Contrary to earlier studies, soluble macromolecules isolated from Lingula shells are shown to specifically promote FAP crystallization by the destabilization of an amorphous calcium phosphate precursor.
