With respect to using the term evolution for linguistic change I am
inclined to think it is appropriate, but of course its association with
the onward-upward character that goes with the term in biology must then
be avoided. As I see it, one of the main factors in linguistic change and
perhaps the main factor is the drive for efficiency in communication which
is dialectically resisted by the need for clarity so that efficiency does
not actually increase andthe actual level of clarity does not change.
Since however change is constant, I believe the term evolution is
appropriate.
 
I believe your characterization of mutual intelligibility as being an
arbitrary criterion is a misconception. After all it concerns
intercommunication, the primary function of language. The difficulty with
mutual intelligibility lies rather in applying it and improvements in that
area could be achieved if the importance of distinguishing languages from
each other could reach the level of attracting financial support. Failing
that we will have to get along with making judgments as we have until now.
 
As for entropy it could not be expected to be found in the structure of a
language since the energy input to maintain clarity prevents observable
change in the direction of disorganization. However within a language
regarded as a closed system, there is (for all practical purposes)
observable changes in the direction of disorganization in
dialectalization as diversification tending toward the shattering of a
language. The opposing force is the rate of interlocution; as that rate
is high it militates against diversification and if it is high
enough, promotes homogeneity and when it is low or decreases is
accompanied by increased dialectalization and if it reaches zero, may
be followed by language fission.
