Thanks Michael, though I do believe there is a specific name for the
condition.

Recalling an earlier converstion on cap, a few days later I picked up an old
text to read on the train and came across something that touches directly on
the idea of developing new ways of understanding molecular biology dynamics.

Memory refresh: I posted about hsp90 and genomic variation via activation of
silent genes.

The text I read had a very interesting article on organic chemistry wherein
the authors stated how they were trying to develop a new model.

Boundaries and Barriers: On the Limits of Scientific Knowledge. Eds. John
Casti & Anders Karlqvist.
Addison-Wesley Publishing.

The relevant article is:

The Barrier of Objects: From Dynamical Systems to Bounded Organizations.
Walter Fontana and Leo W. Buss
