The VLA Development Plan will open new ways to study the evolution of the radio properties of galaxies with redshift directly. The strong (i.e., AGN) radio source population clearly evolves with cosmological epoch- the apparent density of sources increases rapidly with redshift. This also seems to be true for optically selected, often radio weak or silent, QSOs. Not far below the 3CR flux density limit, most sources are at high redshifts ( and many as high as = 3-5). Recently, the IRAS catalog has added a sample in which dust and molecular emission can be detected beyond = 2. Closer by, the Hubble Space Telescope has imaged clusters of galaxies beyond = 0.4, confirming that the Butcher-Oemler effect (the blueing of cluster galaxy populations with redshift) is related to increased star formation in clusters at higher redshifts and that galaxies themselves have different shapes as we look further back. The direct study of the evolution and possibly the formation of galaxies appears to be a real possibility. The enhanced VLA would play a crucial rôle in this arena through detailed exploration of i) the evolution of radio source populations; ii) molecules, dust and free-free emission in distant galaxies; iii) starbursts at high redshifts; and iv) Faraday rotation in magnetized gas-rich environments.
