Extended Data Fig. 6. Low within-population genome-wide diversity is likely the result of selection.
a) The average phylogenetic distance within and between populations along an alignment of all ‘Ca. C. stinkeris’ and ‘Ca. C. noahi’ genomes. The whole-genome alignment was divided into 2.5 kB windows and a phylogenetic tree was calculated for each alignment window. b) The distribution of dN/dS ratios for gene alignments between populations.
