Query: Some Constraints on Galaxy Evolution Imposed by the Specific Frequency
  of Globular Clusters   Early-type dwarf galaxies are found to have high specific globular cluster
frequencies which are similar to the high S values that are observed in
luminous galaxies of types E and S0. It appears unlikely that cluster formation
during mergers between dwarf disk systems can account for the high specific
globular cluster frequency that is observed in early-type dwarf galaxies. Some
alternative scenarios are briefly discussed.
