According to the theory of punctuated equilibrium, evolution will go faster when life has to make rapid changes to survive in challenging environments. Life with an asteroid belt in system can be quite varied and dramatic. Multi-cellular life might need an asteroid belt to provide the right number of hits to spur on evolution.

Chemists are close to showing that DNA could form spontaneously from chemicals which were present during primordial Earth. If they succeed, the work could imply that DNA could predate the birth of life as we know it.
