Left plot: the relative fractions of the different galaxy morphological types as a function of redshift. The total number of galaxies in each redshift step (Δz = 0.2) between z = 1 and z = 3.2 is indicated. The last step includes all galaxies at z > 3.2. The confidence regions reflect both the random uncertainty and the differences between classifications made by three different authors. See the text for more details about the classification procedure. Right plot: same as left, but for a mass complete sample (log (M_⊙ lim) = 10.5). In this plot the redshift step is Δz = 0.5.
