Phylogenetic analysis of SMase D sequences by codon model. Bayesian inference tree based on the codon model. A GTR model was chosen (BIC score = 72,153; lnL = −33,053.48462). Gamma distribution (G parameter = 2.5232). The rate variation model allowed certain sites to be evolutionarily invariable (I). Posterior probabilities are indicated. Loxosceles SMase D Class I isoforms are indicated in clades L and G (red)
