Extended Data Fig. 1: Temporal dynamics of size evolution in each population and treatment group.

Data points show the weighted average radius of cluster size for the entire population. This was calculated by measuring the size of an average of 1150 snowflake yeast clusters per sample population (3 ancestors + 3 treatment groups x 5 replicate populations x 12 time points = 183 samples, all data is publicly available under the raw data file). Please see the Methods section for details on how weighted average radius was calculated.
