Figure 2.

Reproductive fitness of evolved budding yeast lines relative to ancestral reproductive fitness (dashed line). Reproductive fitness increased across all environments. Non-restricted (NR)-evolved lines attained higher reproductive fitness on their home diet than dietary restriction (DR)-evolved lines did on theirs. Meanwhile, lines evolved on DR performed better on their away diet than did NR-evolved lines. In fact, the reproductive fitness of DR-evolved lines was not significantly different on the away diet versus the home diet. Meanwhile, NR-evolved lines exhibited poor performance on their away diet.
