Adaptation requires extra resources or very precise coordination 
with the environment as it changes.   The issue is the ability 
to identify a pattern and predict changes.  These are markov 
problems.   If thriving in an environment requires instrumenting 
the environment to detect emergence, it is quite straightforward 
for a well-adapted system to evolve with the environment.

Are you discussing intelligent adaptation?

cf Tom de Marco's "Slack". Premise: highly efficient organisations
are not adaptive.
