Scientific paper

We will review the chemical evolution of galaxies of different morphological type: spirals, el- lipticals and irregulars, and discuss how chemical abundances can constrain galaxy formation mechanisms. In particular, the following questions will be addressed: can the Milky Way galaxy be the result of merging of dwarf spheroidals? Are the characteristics of spheroids (ellipticals and bulges) more compatible with the monolithic or the hierarchical clustering scenario for galaxy formation? Are population III stars required to explain the chemical properties of stellar popu- lations in galaxies? All of the answers to the previous questions will be negative, thus imposing clear constraints on galaxy formation mechanisms.
