... I will touch upon the following points: ­ fast evolution of the sizes of quiescent (elliptical) galaxies between z = 2 and z = 1; ­ prolonged star formation histories of dwarf spheroidal galaxies in the Local Group; ­ apparent lack of external sources of cold gas accretion for the nearby spiral galaxies; ­ old stellar ages and magnesium overabundance of the large-scale disks of nearby lenticular galaxies. ... This discovery has challenged the recognized scenarios of elliptical galaxy evolution. ...
