Evolution is not primarily driven by the mutation rate. It's primarily driven by differential success of already-existing genetic variation. Over the very, very long term, you need mutation to be the source of that genetic variation, but over the short term mutation is mostly just harmful, and this:
> Like the traits must have already been present in some lower frequency pre crisis, and the crisis distills the traits which are selected for by the crisis.
is correct.
> So probably less evolution moves faster during crisis and more that there is an interesting survivorship bias related to crisis when analyzing the change of a species over time.
This is conceptually wrong; in this context "survivorship bias" bears a technical name you've probably heard of, "natural selection". A stronger survivorship bias means faster evolution.
