We have digressed from the initial topic but that is good for a better understanding of the topic.
What you have simply stated is that in a changing/changed environment, many organisms will not adapt. A small portion would have sufficiently altered genetically to survive. This is certainly clear and is evident.
Organisms like humans are not exactly the same and as genes are mutating simultaneous subtle changes in the environment coupled with varied levels of receptiveness will affect how they mutate.
Many organisms, like people, would not have developed sufficiently in their environment to make the shift/change if/when the environment changes (especially if the change is sudden). Again, is it desirable that all make the shift and why if the answer is yes or no?
You have also explained the biblical statement, "many are called but few are chosen" (just making a link for those with the bible).
The other question/thought should be, why the majority of organisms and people residing in a similar environment are unprepared for change given the fact that change is certain. Can you comment on this?
I do not accept uncertainty as a principle. If they don’t know or are uncertain then it is open to be explained at a later time. Ever heard of the "principle of indeterminacy", all nice ways of saying they don’t know while maintaining academic “respectability”.
