The AS RRM had more differences (i.e., accelerated evolution) in comparison to the CS RRM (i.e., AS RRM: 192 bp, 19.8% sites with substitution, across species = 0.0744 ± 0.0095, K S = 0.4034 and K A = 0.0340; CS RRM: 219 bp, 13.7% sites with substitution, across species = 0.0489 ± 0.0067, K S = 0.2047 and K A = 0.0), and this difference was marginally significant (G 2 = 2.75, p = 0.097).
