Fig. 3

The effect of SMP evolution on the evolution of body mass and mutation rate. a physiological/aging related mortality curves generated based on the cumulative distribution function of DA (Eq. 1). Colors represent the effect of the Som (SMP) parameter (Eq. 1). Dotted lines were generated by elevating mutation rate 2-fold. b modern human mortality in the USA (https://www.ssa.gov). c-e evolution of life history traits under positive selection for body size. f, g population size dynamics when SMP can evolve (corresponds to green in c-e) or SMP evolution is blocked (blue in c-e); colors indicate individual populations. h relative frequency of Species B (SMP evolution blocked, blue in c-e) in a mixed population with Species A (SMP can evolve, green in c-e). For c, d, e and h (and similar graphs in other figures), 25 simulations are combined, with the dark line reflecting the mean and shaded area denoting the 95% confidence intervals. The time scale (1,005,000 units) is universal to all results panels (here, c-g) unless otherwise stated
