... What are their star formation histories? How does this relate to galaxy populations at higher redshift? What, if anything, do we know about the star formation histories of galaxies at high-z? Do low mass and high mass galaxies evolve differently? Can we find a population of galaxies at low redshift which might correspond to a higher redshift population, i.e. the faint blue galaxies? ... What roles do bursts of star formation have in the evolution of dwarf galaxies? ...
