You seem to have misunderstood the basics of our evolutionary-cybernetic
approach. Metasystem Transition Theory is interested in the *evolutionary
origin of control*. That is, evolution does not have a goal or target
state, but tends to produce systems which do have a goal, i.e. control
systems. The reason is the mechanism which D.T. Campbell called a
"vicarious selector" (http://pespmc1.vub.ac.be/VICARSEL.html). Natural
selection will eliminate all systems which are unfit or not adapted. A
system does not a priori know what is fit and what is not. Therefore, it
can only blindly try out something and hope that it works. It it does not
work, the system may not survive.

It would be obviously much more efficient if the system would already have
some idea of which action is appropriate in which circumstance, i.e. if it
would be able to internally select the right actions, in anticipation of
natural selection by the environment. This means that the system needs to
somehow interiorize selection, i.e. it must develop an internal standard or
evaluation criterion to distinguish between what is good (fit) or bad. This
is the same as having an implicit goal. All actions of the system will be
selected such that they try to maximize this internal criterion, in spite
of changes in the environment. Thus, a system which is good at surviving
natural selection will also tend to be a control system.
