  Comparison of our chemically consistent models for spiral galaxies with
observed DLA abundances shows that at high redshift DLA galaxies may well be
the progenitors of normal spiral disks of all types from Sa through Sd. Towards
lower redshifts z </= 1.5 however, early type spirals drop out of DLA samples
due to low gas or/and high dust content. We use the spectrophotometric aspects
of our unified spectral, chemical, and cosmological evolution models to predict
expected luminosities in different bands for DLA galaxies at various redshifts
and compare to the few optical identifications available.
