Descripción
Dwarf galaxies in the Local Group allow to study in great detail the
physical mechanisms responsible for the formation and evolution of
galaxies. In fact, their resolved stellar populations allow to unveil
their star formation and chemical evolution histories back to the
earliest epochs. In particular, they can be used to constrain the
efficiency of both local (Supernovae, SN) and global (reionization)
mechanisms. The most isolated galaxies are the particularly interesting
because, not having suffered strong interactions with the giant
galaxies, they are free from environmental effects and they are ideal
probes to test the early evolution of dwarf systems. I summarize here
some of the latest results concerning isolated galaxies in the Local
Group, with particular enphasis on the result of the LCID project.
