In the recent years, intermediate redshift (0 to 1) galaxies have been
observed in various deep fields, allowing the determination of stellar
masses, star formation rates (SFR), and their distribution. One of the
interesting results from these studies is the fact that the stellar mass
function for star-forming galaxies is ~ constant. I will show how this
fact can be coupled with backward models of the evolution of our
Galaxy and spiral galaxies in order to bring insights in the cosmic
history of galaxies and the cosmic fate of Milky Way siblings. Another
application is the comparison of these stellar masses and SFR functions
with those obtained for Gamma Ray Bursts (GRB) host galaxies. I will
show that this comparison allows us to characterize the variation of the
GRB bias with the metallicity of the progenitor.
