In this paper we briefly review some of the most recent developments concerning the formation of the first luminous objects in the universe, to which we refer to as Pop III objects, and their observable effects. In particular, we try to critically discuss the possible connection between them and dwarf spheroidal galaxies. We come to the conclusion that, if the properties of Pop IIIs are correctly predicted by hierarchical cosmological models, their identification with present day dwarf galaxies presents several difficulties.
