Figure 1. Total number of mutations over time in the 12 LTEE populations.

Figure 1

a, Total mutations in each population. b, Total mutations rescaled to reveal the trajectories for the six populations that did not become hypermutable for point mutations, and for the other six before they evolved hypermutability. Each symbol shows a sequenced genome; some points are hidden behind others. Each line passes through the average of the genomes from the same population and generation.
