Distribution of E. coli mutation rates estimated in rich media and published from 1943 to 2016 (re-plotted from ref. [6], N = 111). Broth—rich nutrient medium, LB—rich lysogeny broth medium. These data also include a range of genotypes and phenotypic markers (Supplementary Data File). Note the nonlinear axes
