Abstract
The number density of the high-redshift (z >2) galaxies discoveredover the last few years with the Lyman-break technique is only afactor of a few lower than the number density of galaxies in the LocalUniverse. Thus, understanding the properties and the nature of thesehigh-redshift systems is instrumental to our understanding of thecosmic evolution of galaxies and their stellar content. I brieflyreview the observed characteristics of the Lyman-break galaxies,relate these galaxies to their most likely low-redshift counterparts,and discuss the implications of dust obscuration on the globalproperties of the Lyman-break population. Finally, the observationalproperties of the high-redshift population are set in the framework ofa simple evolutionary model for the stellar, metal and dust content ofgalaxies, to derive the intrinsic star formation history of theUniverse.
