Two Points

Yes, that is essentially Muller's idea. But both you and Tom should

be aware that driving a chemical cycle by an environmental cycle is

more difficult than it sounds.

TOM:
It's impossible any other way. Do you know of any scenario where
there is no variation in temp? How do you get variants in no
variation. There is no scenario known that does not have
an environmental cycle that I know of. What can you suggest
otherwise?

ISTM that you need two environmental variables, both cycling, but 90 degrees

out of phase with each other. And you need other stuff too. You need

to distinguish two kinds of "enhancement" - kinetic and thermodynamic.

Muller appears to realize this, but ISTM that you and Tom do not.

TOM
Well in the above if you are admitting the need for environment
variation for variants - and that is based on the sun/heat cycle,
then I agree.
Now what 'other stuff' is outside of that sun/heat cycle?
