Sustained fitness gains and variability in fitness trajectories in the long-term evolution experiment with Escherichia coli
Richard E Lenski, Michael J Wiser, Noah Ribeck…·Neerja Hajela
The paper extends a previous study on Escherichia coli evolution, showing that fitness continues to increase over 60,000 generations with power-law dynamics and population-specific variability.
