## to 9 I have objections. I cannot imagine (maybe my mistake)
evolution without a goal, a final aim which would require an
intelligent design to approach it. (I may have one: the
re-distribution into the Plenitude). My way (as of yesterday) is the
ease-and-potential path of changes allowed by the available
configurations (relations) when a change occurs.
NO RANDOM, it would make a grits out of nature. Even authors with high
preference on random treatises withdrew into a "conditional random"
when I attacked the term. Conditionality kills random of course.
So in my terms: NO random mutations, (especially not FOR survival) I
call 'evolution' the HISTORY of our universe. The unsuccessful mutants
die, the successful go on - science detects them in its snapshots
taken and explains them religiously. (Survival of the fittest - the
Dinosaur was fit when it got extinct by the change in circumstances).
I accept ONE random (in mathematical puzzles): "take ANY number..."
Your "lower, but not upper bound" is highly appreciable. Thanks.
I apologize for my haphazard remarks upon prima vista reading. The
list-discussion is not a well-founded scientific discourse upon new
ideas. Most people tell what they formulated over years. A reply is
many times instantaneous.

I wanted to make a remark on just this part of your post as I need
to ask a question. Why is the Selective aspect of evolution almost
completely ignored? It is easy to talk about mutations and models of
them, such as random walks - which I favor!, but what about the
selection aspect? what about how the Tree of Life is almost constantly
pruned by events that kill off or otherwise blunt growth in some
directions as opposed to others?
My question to you is specific. How do polymers mold themselves to
local parameters that influence their molecules? What determines their
shape? Is there a deterministic explanation of the shape of a polymer?
Would this explanation work for, say, DNA or peptite molecules?
