1 Figure 11. This figure shows the results of additional simulations where the decay rate of double-stranded molecules is reduced by a factor of 10 relative to that of single-stranded molecules. The figure is referred to in the Authors' response to Reviewer's report 3.

2 Figure 12. This figure shows the additional results that reveal a non-linear anti-correlation that evolves between kSP and kDP as a result of diverging selection under finite diffusion. This figure is referred to in the section, ''The effect of biases in the replication rates of single strands (a case where kSP kSM')".

3 The description of the ODE model with complex formation for a system of two replicator species.
