Secular Evolution of Galaxies: From Dark Halos to Nuclei

'One path by which disk galaxies evolve is via internal secular evolution. By breaking the symmetry of the system, bars play an important role in driving such evolution. I describe some recent results concerning aspects of this evolution relating to dark halos, disk density profiles, bulges and central nuclei.'
