You are right but I think my argument still stands in that the Darwinian concept of natural selection in a Uniformitatarian construct is being discarded. I do Metaphysics not Physics so my terminology may be behind. You simply made the point better than I could in that we see species change when there is an external stressor that causes the environment to rapidly change and thus animals and plants to have to adapt or die not in a slow gradual process envisioned by Darwin.
It might (actually, I would theologically expect that, but for sake of discussion I say “might”) never be possible for science-as-we-know-it to fathom some of the mysteries of creation or even how the world has been kept up. So I have to give an emphatic “maybe” to both the YEC and OEC crowds. They eventually both end up pushing into areas of dubious reasoning.
Scriptural accounting embraces a number of periods each having certain unique characteristics. Pre-Edenic, Edenic, pre-Flood, Flood, post-Flood, and (eschatologically) more.
Details aside, it is philosophically clear the present world is in fact “subject to frustration.” Our lives, with all their amazing capabilities, simply seem doomed to nothing, as inexorably as rot or as the death of the stars.
Metaphysics is not science, and any terminology associated with it is not applicable to science. Whatever "Uniformitatarian" means, it is not a scientific term.
Also, strictly speaking, there is no adaptive evolution. Whenever reproduction occurs, mutations occur--the accumulation of DNA mutations is the mechanism of evolution. Either an organism with its specific set of mutations (all organisms have mutations in their genetic material) can survive and reproduce in a specific environment, or it can't. If it cannot survive, its mutations will not remain in the population. If it can survive, its mutations might remain in the population. If its specific mutations give it a survival advantage in that environment, then its mutations will probably spread throughout the population. Not all mutations are lethal, or even have much of an effect. Some mutations have a survival disadvantage in one environment, and advantage in another. In any case, whatever the effect (if any) is of a mutation, it is not adaptive.
