In my talk I will review the semi-analytic (SAM) approach to galaxy formation discussing its strengths and weaknesses. I will use SAMs to focus on the high redshift universe, in particular investigating the high specific star formation rates of galaxies and the high velocity dispersions in them. Furthermore, I will focus on several aspects of the formation and evolution of early-type galaxies such as their size-evolution with redshift and their assembly history. During my talk I will put special emphasize on showing how SAMs can be used to make predictions apart from reproducing already existing observations.
