Experimental data from Runs 1 and 2 of the CastNet proof-of-concept. A–D shows results for Run 1 (stringent selection), and E–H for Run 2 (no selection). A and E show the target phylogenies, B and F the gene trees, C and G the mean population fitness progression (sampled every 100 generations, for 20,000 generations), and D and H in what proportion of the population each gene was expressed
