It is known for sometime that extreme black holes and branes exhibit

(super)symmetry enhancement near horizons. This observation underpins

AdS/CFT and many of the conformal techniques that have been used

for black hole micro-state counting. I shall demonstrate that this symmetry

enhancement is a rather generic dynamical phenomenon which relies on the

smoothness of the field configurations. The proof involves generalizations of

the Lichnerowicz theorem and the use of index theory.
