:-) I see your point. (Although it looks like you may have meant 'avoid'
in the second sentence instead of 'evolve.') I think the interaction
between the genome and the outside environment is really interesting,
especially in terms of some evolutionary effects which come from that,
like the one (can't remember the name) which allows adaptive organisms
to see a smoother incline around an otherwise-sharp fitness peak by letting
them learn it. Also the 'pre-adaptive' sorts of effects which I think
are interesting, and so on.

The interaction between cell and genome seems to me likely *more*
complicated than a view in which the DNA is the code and the cell is a
kind of all-purpose DNA-decoding-machine. I think the tendency is to
forget that not only DNA is passed to offspring, but a whole cell, with
all its machinery and everything, and also a situation--a large
environmental situation in which the parent lived. This can include a
very complex social structure for some animals.
