The classification scheme does not use galaxy colours, hence it does not bias against young stellar populations. The 249 galaxies (i_AB<24) paint a complex formation picture. Their stellar populations show gradients which readily rule out a large range of ages among and within galaxies. On the other hand, there is a decrease in the comoving number density, which suggests a strong bias when comparing local and distant early-type galaxies. This bias can be","authors_text":"A.
