If Rock n Roll came from the Blues, why is there still the Blues?

The creation of a new form from an existing one does not necessitate the elimination of the older form.

The question itself is based upon a flawed premise based upon a misunderstanding of evolution. There is no natural tendency for a chimpanzee to become more like a human, or for things to get unambiguously improved over time. Yet this is a very seductive misconception.
