Cells with the "wrinkly spreader" phenotype formed a mat on the surface of the medium in the static cultures. This allowed for them to outcompete the smooth colonies and have a selective advantage in that particular environment. However, they had a selective disadvantage in the turbulent environment of the shook cultures.
