The broom of the system: Tracking soft selective sweeps in bacteria colonizing the gut

A growing body of population genetic evidence suggests that adaptive evolutionary change often proceeds via soft selective sweeps, in which beneficial mutations on multiple genetic backgrounds—and potentially at multiple loci—all increase in frequency, but none achieve fixation. This process has … Continue reading
