We present a generic framework, "baryomorphosis", which modifies the baryonasymmetry to be naturally of the order of a typical thermal relic WIMP density.We consider a simple scalar-based model to show how this is possible. Thismodel introduces a sector in which a large initial baryon asymmetry is injectedinto particles ("annihilons") phi_B, \bar{phi}_B of mass ~ 100 GeV - 1 TeV.phi_B-\bar{phi}_B annihilations convert the initial phi_B, \bar{phi}_Basymmetry to a final asymmetry with a thermal relic WIMP-like density. Thissubsequently decays to a conventional baryon asymmetry whose magnitude isnaturally related to the density of thermal relic WIMP dark matter. In this waythe two coincidences of baryons and dark matter i.e. why their densities aresimilar to each other and why they are both similar to a WIMP thermal relicdensity (the "WIMP miracle"), may be understood. The model may be tested by theproduction of annihilons at colliders.
