摘要：We will review the chemical evolution of galaxies of different morphological type: spirals, ellipticals
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 populations
in galaxies? All of the answers to the previous questions will be negative, thus imposing
clear constraints on galaxy formation mechanisms.
