A basic technique used in the experiments that produced stationary-phase
mutations was to engineer a mutation and then supply the bacteria only with the
product they had become dysfunctional for.
When this happened the bacteria entered a starvation or "stationary-phase"
and stopped replicating. It was while in this non-replicating state that the
engineered mutations were reversed leading to the original interpretation of
Model of an Internal Evolutionary Mechanism (presented as an extension to
Homoeostasis) and proposed method of testing.
