One of the greatest challenge faced by cosmology today is to reconcile the large scale structure formation theory with galaxy number counts. At the low end of the galaxy luminosity function, this discrepancy reaches several orders of magnitudes, probably due to the lack of any satisfactory galaxy formation theory.
Studies of nearby low luminosity dwarf galaxies has shown that these objects should not be considered as isolated but that their environment plays an important role in their evolution. In this presentation, I will review some of these evidences and describe how our local neighborhood can be used to constrain galaxy formation and evolution theories.
