That depends upon what you mean by 'conceptualize' and 'idea'. ;-) It is
important not to fall into false dichotomies about cognition. Even when
we talk about human cognition, cognitive skills are amazingly
differentiated. The Swiss Army knife metaphor of evolutionary psychology
may be a bit strained, but things are not black and white.
I vaguely recall an experiment that purported to show modus ponens logic
in rats, using a complex maze. The rats learned A -> B and then B -> C
and showed evidence of knowing A -> C. But, as we know from experiments
with humans, that is not enough to show abstract thinking. ;-)
Rats also exhibit a curious behavior when learning T-mazes. When they
reach the cross point of the T, they may stop and look left and right a
few times. Even the behaviorists called this "vicarious trial and error."
Now, if a human did that, we would say that he had two opposing ideas in
his head. What do we say about rats?
You raise some interesting points in your next paragraph. It's not that
I don't have some thoughts about them, but there's too much there for me
to address here and now.

It makes perfect sense to me. What do you want to focus on in the
genotype/phenotype analogy? If it is internal vs. external, then the
external manifestation corresponds to the phenotype. If it is the
process of copying, then the external manifestation corresponds to the
genotype. <shrug> I agree with you. Better not use the analogy.
