No correlation between pairwise evolutionary distances across the phylogenetic tree and difference in CAI
values of pairs of organisms. Scatter plot of the difference in CAIave values between each pair of two organisms in our data (x-axis) and their phylogenetic distances (y-axis). CAIave is indicated as 'Average CAI'. The pairwise distances across the phylogenetic tree were based on the tree generated in  and computed as the path length between two organisms through the most recent common ancestor. CAI, Codon Adaptation Index.
