The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is a quantum computer.
Seth LloydIf you take a more Darwinian point of view the dynamics of the universe are such that as the universe evolved in time, complex systems arose out of the natural dynamics of the universe.
