That's very close to what I was trying to say, only in just the reverse:
genetic-change is not the product of mass die-offs or survival.
Genetic change may happen, but it's not caused (or guaranteed, or even
prompted to go in a positive or a negative direction) by extinction
events. The extinction of one sub-group does not automatically add
improvement to the surviving group.
