Understanding galaxy evolution requires understanding the impact of cosmic time, environment, mass, and halo growth at least, because likely a combination of them leads to the quenching of star formation and the emergence of the galaxy populations we see in the nearby Universe. In the talk, I will present the picture coming out from two mass-selected samples of red-sequence early-type galaxies in the general field and in clusters over the redshift range 0<z<2. With this sample, I isolated the effects of the halo in which galaxies are embedded and whether its role has changed in the last 10 Gyr.
