*The log-likelihood values and parameters estimated were computed using
codeml implemented in PAML 4.9. PSSs were inferred in model M8 by BEB
with posterior probabilities > 95%.
Usually consistent with the above finding, every substitute test (MEME,
SALC, FEL, and FUBAR) for positive selection implemented in online
adoptive evolutionary server Datamonkey (Weaver et al., 2018) identify
numerous codons under positive selection (Figure 2).
