Reduced selection during sweeps lead to adaptive momentum on rugged landscapes

The paper identifies 'adaptive momentum' as a dynamic where selective sweeps reduce purifying selection, allowing populations to explore fitness valleys and access new fitness peaks.

Moderate amounts of epistasis are not evolutionarily stable in small populations

The paper shows that moderate epistasis is not evolutionarily stable in small populations, as high mutation rates lead to shifts toward either lower or higher epistasis depending on initial conditions.

Mapping the Peaks: Fitness Landscapes of the Fittest and the Flattest

The paper analyzes the mutational neighborhoods of fit and flat genotypes in a digital evolution system to understand the genetic basis of mutational robustness and the survival of the flattest effect.

Evolution of Drift Robustness in Small Populations

This study shows small populations evolve drift robustness by adapting to drift-robust fitness peaks, reducing vulnerability to drift-related fitness declines.
