Sketch of the experimental setup. a Sampling design of the 12 bacterial lines evolved over the 39 days of the experiment. The vertical dashed grey line represents the transfer of the lines to a new agar plate, which occurred every three days. Blue dots indicate that the DNA of this line was extracted and sequenced at this time. b We transferred about one million cells taken from a random point on the edge of the colony after three days of growth to the center of a new agar plate. c The periodic transfer occurring every three days without any strong bottleneck aims at mimicking a continuous expansion in space
