Maximum likelihood analyses using different evolutionary models. Trees A-C were calculated using the first- and second-position Goremykin et al. [19] matrix. Tree D was calculated using all three codon positions. All trees were built using ML with the HKY85 model and the following treatments of rate heterogeneity: A. No rate categories. B. Four gamma-distributed rate categories. C. Estimated proportion of invariant sites (no gamma rate categories). D. No rate categories (all three positions). Parameters were estimated separately for each analysis as described in Methods.
