Fig. 2From: Evolving mutation rate advances the invasion speed of a sexual speciesExperiment 1: fixed mutation rates. The range border position in time (horizontal axis) is shown, averaged over 200 simulations for the original experiment (with evolving dispersal probability) in panel a for the case with evolving mutation rate (‘control’) and fixed mutation rates of 10−4 and 10−5. Panel b is the same, but for a fixed dispersal rate of 0.2Back to article page
