Faint blue counts are interpreted as being due to dwarf elliptical galaxies undergoing their initial starburst at z of about 1. The starburst epoch is determined by the decline in the UV background, which results in the stably confined photoionized gas in dark halos of about 10 exp 9 solar masses being able to cool and settle in the center of the halos and undergo star formation. The evolution of these dwarfs are found to be strongly influenced by the local intergalactic medium; those in high-pressure environments will be preserved while those in low-pressure regions will fade away. The present-day dwarf ellipticals are identified as the surviving members of the original population, and it is suggested that their spatial distribution as well as their distributions of mean colors and metallicities reflect their environmentally influenced star-formation history.
