Abstract

I report on the recent discoveries of the Red Giant Branch Bump(s) in many dwarf Spheroidal galaxies of the Local Group. The perspectives for the use of this new observational feature to obtain constraints on the Star Formation History and Age-Metallicity Relation of nearby galaxies are shortly explored and reviewed.
