In this paper we review the current ideas about the formation of our Galaxy. In particular, the main ingredients necessary to build chemical evolution models (star formation, initial mass function and stellar yields) are described and discussed. A critical discussion about the main observational constraints available is also presented.

Whereas 'natural evolution' is a well-studied biological theory, the notion of 'chemical evolution' remains ambiguous. At least two major meanings of 'chemical evolution' can be found. As used by cosmologists, planetologists or geochemists among others, chemical evolution - call it chemical evolution1 - refers to the changes in chemical composition of ...

The subject of Galactic chemical evolution is now in a very confused state, because of the freedom exercised by theoreticians in choice of assumptions and because of ambiguities in observational data. Nevertheless a few conclusions can be put forward at this time:- i) the “Simple Model” still has a considerable field of applicability, especially ...

Cosmic chemical evolution describes the chemical enrichment occurring in a unitary comoving volume of the Universe as a function of cosmic time. While galactic chemical evolution concerns single galaxies, cosmic chemical evolution refers to a mixture of galaxies of different morphological type whose contributions to chemical enrichment are weighted ...
