Table 1. Summary of likelihood-ratio tests performed using branch-site models implemented in PALM. Log-likelihood values of different models tested using Amphisbaena, Serpentes or Gymnophiona labeled as foreground branches. LnL corresponds to the likelihood value. Sites inferred under positive selection in Serpentes had posterior probabilities values of 0.64, 0.76 and 0.51, respectively.
