Yes and no. Evolution is incomplete. But we have actually personally witnessed a natural selection process that lead to adaptive changes in real time. We know that things do evolve, even if the higher level genetic change is not just natural mutation, and the origin of DNA and the cell is unknown. We do have a direct data point for adaptive DNA change.
And I say string theory, but it is possible that any of those suddenly get a direct measurement, despite how unlikely that appears. There is a way string theory can be supported, and it might be possible to directly measure conciousness, or spacetime. But it doesn't appear so right now.
