Figure 1

Effect of 10,000 generations of evolution on total catabolic function. Each point is the weighted average of performance on 68 substrates; 1.0 is the ancestral value. The evolved populations (circles) had significantly lower diet breadth (t = 9.49, df = 11, p < .0001, one-tailed) than the mean of the common ancestors (ANC, triangle). Error bars are standard errors.
