I'm not sure how you relate growth to internax/external control. Could you
explicate?

Yes, but as I see it there are TWO paths to autopoiesis. One, evolved from a
purely dissipative structure, and two, evolved from dissipative replicating
systems. Now, both involves evolution in a sense, but only one of the paths
involve self-replication.

I think it is dangerous to say that evolution = reproduction. It is fully
possible to conceive of an evolving system that does not self-replicate.
