The BCS theory of fermionic pairing and condensation is used to understand the interacting boson model. Results from BCS are incorporated in an effective Hamiltonian that after symmetry-breaking and second-order corrections yields an IBM-type Hamiltonian with coeefficients determined by well-known nuclear constants. The /ital O/(6) and /ital O/(5) chains are shown to be largely of spontaneous origin. Supersymmetry aspects of the model are also discussed. /copyright/ Academic Press, Inc. 1989
