  The classical picture of GUT baryogenesis has been strongly modified by
theoretical progress concerning two nonperturbative features of the standard
model: the phase diagram of the electroweak theory, and baryon and lepton
number changing sphaleron processes in the high-temperature symmetric phase of
the standard model. We briefly review three viable models, electroweak
baryogenesis, the Affleck-Dine mechanism and leptogenesis and discuss the
prospects to falsify them. All models are closely tied to the nature of dark
matter, especially in supersymmetric theories. In the near future results from
LHC and gamma-ray astronomy will shed new light on the origin of the
matter-antimatter asymmetry of the universe.
