  I review the general progress made in the study of galaxy evolution
concentrating on the impact of systematic ground-based spectroscopic surveys of
faint galaxies and high resolution imaging with Hubble Space Telescope. The
picture emerging is one where massive regular galaxies have changed little
since redshift $z\simeq$1, whereas there has been a marked decline in the
abundance of less massive star forming dwarf galaxies. Reconciling these trends
with the conventional hierarchical growth of structure on galactic scales and
determining the fate of the star forming dwarfs remains a major unsolved
problem in contemporary cosmology
