Model Predictions for Clustering and Morphologies at HDF depths

The current status of numerical simulations of the formation of galaxies is reviewed. Success and failure of modeling galaxies at low and high redshift is demonstrated using a variety of examples, such as the Tully-Fisher relation, the appearance of high-redshift galaxies and the kinematics of damped Lya systems. The relationship between the clustering properties of high-z galaxies and the present generation of galaxies is emphasized.
