[Paleopsych] is evolutionary change stockpiled?

[Greg Bear]

Excellent ideas.

We can imagine a kind of churning hypothesis-engine in the genome,
constantly error-correcting, murmuring on about possible change, rather like
the voices in the back of our heads that we never act upon! I've called it
the Wizard in the Genome.

We can imagine such--but how fanciful is such an idea? What kind of research
would need to be done to even begin to find the effects of such operations?
Would it lie in RNA expressions, RNAi, or in protein modifications, or both?

Perhaps the old RNA world is still the strawboss in this entire picture.

One "reason" for doing this would be that
any change that challenges the genome
might not persist.  So a solution might
be prepared but not implemented until
there were more data points to justify it.

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...

Best wishes!

Could be.  Check with Greg Bear.
