E.coli Follows Pareto's principle!

To follow Pareto’s principle like an ant society, our model system must follow the three conditions shown in Fig. 1 to 3. In our model, all individual cells have the same genetic circuits but take two states, A (worker) and B (idler), depending on the surrounding circumstances.

As shown in Fig. 1, 2, and 3, the condition of the system is changing as follows:
Bistable state ⇒ The removal of A (worker) ⇒ Regain of "stable coexistence

Fig. 1 Condition 1. Bistable state
The system is stable when it contains both A (worker) and B (idler) at certain ratio.

Fig. 2 Removal of A
By removal of A (worker), "stable coexistence" of the system is broken.

Fig. 3 Condition 3. Regain of "stable coexistence"
Some B (idler) changes to A (worker) while the others remain B (idler). Then the system regains "stable coexistence".
