Appendix 1—figure 6. Changes of SMST over time for different trade-off parameters $\delta$ but fixed lifespan $\lambda$ in each plot.

For very large $\delta$ diverse strategies cannot be adopted. For the smallest $\delta$ diverse strategies can emerge easily, but among them extreme strategies (Darwinian Demons) very quickly dominate leading to low diversity. Sustainable diversity emerges for moderate values of $\delta$. Very short lifespans $\lambda$ prevent increase in diversity, especially for big trade-offs (zero SMST for $\lambda =10$ and high $\delta$). Simulations were done with $\mu =0.001$ and $m=0.02$.
