We present a scenario in which a remarkably simple
relation linking dark matter properties and neutrino masses
naturally emerges. This framework points towards a low energy
theory where the neutrino mass originates from the existence of a
light scalar dark matter particle in the MeV mass range. A very
surprising aspect of this scenario is that the required MeV dark
matter is one of the favored candidates to explain the mysterious
emission of 511 keV photons from the center of our galaxy. A
possible interpretation of these findings is that dark matter is
the stepping stone of a theory beyond the standard model instead
of being an embarrassing relic whose energy density must be
accounted for in any successful model building.
