Figure 6. Dependence of mean fitness on fidelity.
A: Mean fitness as a function of 
at constant 
. The slope 
is negative below a threshold 
for each 
(white dashed lines in Figure 5A,B and green dashed lines in Figure 5C,D, respectively). The discontinuous jump for 
and the cusps at smaller 
values correspond to G-L and L-C transitions, respectively. B: Mean fitness averaged over starvation processes (
) for different initial thermodynamic force 
(see Figure 10). The slope 
is negative below a threshold 
for each 
(green dotted lines in Figure 5A,B). Vertical lines represent the nonenzymatic fidelity. The fitness 
is in units of 
.
