Surface brightness evolution has been detected in elliptical galaxies (consistent with passive evolution models of old stellar populations) and in disk galaxies (presumably due to enhanced star-formation rates). The rates of evolution in clusters and the field are not measurably different. In addition to this similarity, the high-redshift populations in both environments exhibit a ``blue-excess'' population, increased rates of star formation, and high frequency of peculiar structure. Thus, there are several parallels between evolving cluster and field galaxies and the high-redshift cluster environment will be understood only by comparison with the field population at the same epoch.
