Query: A simple model for the evolution of molecular codes driven by the
  interplay of accuracy, diversity and cost   Molecular codes translate information written in one type of molecules into
another molecular language. We introduce a simple model that treats molecular
codes as noisy information channels. An optimal code is a channel that conveys
information accurately and efficiently while keeping down the impact of errors.
The equipoise of the three conflicting needs, for minimal error-load, minimal
cost of resources and maximal diversity of vocabulary, defines the fitness of
the code. The model suggests a mechanism for the emergence of a code when
evolution varies the parameters that control this equipoise and the mapping
between the two molecular languages becomes non-random. This mechanism is
demonstrated by a simple toy model that is formally equivalent to a mean-field
Ising magnet.
