[Paleopsych] is evolutionary change stockpiled?

It's a provocative idea, isn't it? Invisible mutations, occurring at the
metabolic level, in the "infrastructure," so to speak, but not manifesting
in large-scale phenotypic changes.
However, I think it's also apparent that all organisms today have a set of
"grammatically correct" bauplan variations that can be called upon in
incremental (but not gradual) stages in response to environmental challenges
over perhaps hundreds or thousands of years in larger animals, and tens of
years in insects, and days or weeks in bacteria.
The best recent example is the reoccurrence of wings in stick insects...

Could be. Check with Greg Bear.
