But this (a listing of illustrations of how the genome can change other than by mutations) doesn't constitute a crisis—it's a very interesting finding that shows that variation in a genome can arise by processes other than mutation of an organism's own DNA. The disposition of that variation still must occur via either natural selection (it can be good or bad) or genetic drift (no effect on fitness). This hasn't really changed the theory of evolution one iota, though it's changed our view of where organisms can acquire new genes.
