Table. Estimates of Average

Evolutionary Divergence over Sequence Pairs within Groups
The number of base substitutions per site from averaging over all sequence pairs within each group are shown. Standard error estimate(s) are shown in the last column. Analyses were conducted using the Maximum Composite Likelihood model [1]. The analysis involved 23 nucleotide sequences. Codon positions included were 1st+2nd+3rd+Noncoding. All positions containing gaps and missing data were eliminated. There were a total of 2306 positions in the final dataset. Evolutionary analyses were conducted in MEGA7 [2].

Table. Estimates of Evolutionary Divergence over Sequence Pairs between Groups
The number of base substitutions per site from averaging over all sequence pairs between groups are shown. Standard error estimate(s) are shown above the diagonal.

the Neighbor-Joining method [1]. The optimal tree with the sum

of branch length = 2.17322002 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (500 replicates) are shown next to the branches [2]. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the Tamura-Nei method [3] and are in the units of the number of base substitutions per site. The rate variation among sites was modeled with a gamma distribution (shape parameter = 4). The differences in the composition bias among sequences were considered in evolutionary comparisons [4]. The analysis involved 31 nucleotide sequences. Codon positions included were 1st+2nd+3rd+Noncoding. All positions containing gaps and missing data were eliminated. There were a total of 2241 positions in the final dataset. Evolutionary analyses were conducted in MEGA7 [5].
