FIG 1.
Association between sequence divergence and dN/dS ratio. A comparison of dN/dS ratios in recently emerged coronaviruses (red circles), other human coronaviruses and relatives infecting other species (blue circles), and a collection of bat sarbecoviruses (SARS-like) (pink circle). A power law line of best fit showed a significant correlation between divergence and dN/dS ratio (P = 0.000006). Sequences of the three data sets of EBOV control sequences were included (gray triangles).
