Abstract
The abundance of elliptical, S0 and spiral galaxies in clusters is presented as a function of redshift comparing the results of the HST distant cluster studies with new data at z~0.2 and with the standard local comparison samples. This analysis confirms and strengthens the conclusion that the proportion of S0 galaxies increases toward lower redshifts at the expense of the spiral population. The dependence of the relative occurrence of S0s and ellipticals and of the morphology-density relation on the cluster concentration are also discussed.
