We carried out a photometric and structural analysis in the rest-frame $V$band of a mass-selected ($\log M/M_\odot >10.7$) sample of red-sequencegalaxies in 14 galaxy clusters, 6 of which are at $z>1.45$. To this end, wereduced/analyzed about 300 orbits of multicolor images taken with the AdvancedCamera for Survey and the Wide Field Camera 3 on the Hubble Space Telescope. Weuniformly morphologically classified galaxies from $z=0.023$ to $z=1.803$, andwe homogeneously derived sizes (effective radii) for the entire sample.Furthermore, our size derivation allows, and therefore is not biased by, thepresence of the usual variety of morphological structures seen in early-typegalaxies, such as bulges, bars, disks, isophote twists, and ellipiticygradients. By using such a mass-selected sample, composed of 244 red-sequenceearly-type galaxies, we find that the $\log$ of the galaxy size at a fixedstellar mass, $\log M/M_\odot= 11$ has increased with time at a rate of$0.023\pm0.002$ dex per Gyr over the last 10 Gyr, in marked contrast with thethreefold increase found in the literature for galaxies in the general fieldover the same period. This suggests, at face value, that secular processesshould be excluded as the primary drivers of size evolution because we observedan environmental environmental dependent size growth. Using spectroscopic agesof Coma early-type galaxies we also find that recently quenched early-typegalaxies are a numerically minor population not different enough in size toalter the mean size at a given mass, which implies that the progenitor bias isminor, i.e., that the size evolution measured by selecting galaxies at theredshift of observation is indistinguishable from the one that comparesancestors and descendents.
