    • This result is also surprising in the diminishing-returns models because we expect fewer beneficial mutations to fix in high-fitness backgrounds where they provide a smaller selective advantage. This puzzle is related to the observation (25) that fixation rates in long-term evolution of E. coli are constant through time despite a declining rate of fitness increase. However, our result would be consistent with the diminishing-returns models if the beneficial mutation rate is also higher in high-fitness backgrounds.

    • These are likely enriched for the most strongly beneficial mutations. Hence, if modular epistasis is prevalent, it is among these mutations that we expect the strongest trend.
