1. HKY = Hasegawa-Kishino-Yano model [78]; K80 = Kimura 2-parameter [79]; Γ = gamma distribution.
* 1 = one model for the whole gene.
+ 3 = partition of the data per codon position.
§ Values represent twice the loge of the Bayes factor (B10) in the comparison of models M0 and M1 (2*loge B10). Positive values below 2 indicate no evidence against M0 [71,80]
