Figure 7From: In silico ribozyme evolution in a metabolically coupled RNA populationThe effect of the length penalty (b 2) on replicator evolution. A: the stationary frequencies of replicator types (triangles: the proportion of surviving systems out of 100 parallel simulations); B: the averages of available enzymatic activities; C: the average length of replicator types. Data points recorded at generation T = 106. Colour code as in Figure 4. Fixed parameters: h = 3×3, D = 4.Back to article page
