  I review the subject of the cosmological evolution of galaxies, including
different aspects of growth in disk galaxies, by focussing on the angular
momentum problem, mergers, and their by-products. I discuss the alternative to
merger-driven growth -- cold accretion and related issues. In the follow-up, I
review possible feedback mechanisms and their role in galaxy evolution. Special
attention is paid to high-redshift galaxies and their properties. In the next
step, I discuss a number of processes, gas- and stellar-dynamical, within the
central kiloparsec of disk galaxies, and their effect on the larger spatial
scales, as well as on the formation and fuelling of the seed black holes in
galactic centres at high redshifts.
