A phylogenetic tree for the sequences that form the shared green edge in Figure 5. Labeling matches that in Figure 5, except that sequence B4 threads through the shared green edge twice, giving two sequences labeled B41 and B42. We remark that the ten sequences show few substitutions; consequently, the topology of this tree is rather reliable despite the fact that the sequences are very short.
