FIGURE 4. Neighbor-Joining phylogenetic tree of Namanereis hummelincki (USNM 1283368) from Montserrat and similar sequences. The evolutionary history was inferred using the Neighbor-Joining method (Saitou & Nei 1987) The optimal tree with the sum of branch length = 0.66065705 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches (Felsenstein 1985). 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 p-distance method (Nei & Kumar 2000) and are in the units of the number of base differences per site. The analysis involved 11 nucleotide sequences. Codon positions included were 1st+2nd+3rd+Noncoding. All positions containing gaps and missing data were eliminated. There were a total of 585 positions in the final dataset. Evolutionary analyses were conducted in MEGA6 (Tamura et al. 2013).
