Figure 5

Bootstrapped ML trees derived from a reduced clade A dataset and sequences derived from evolutionary simulations. The tree depicting the reduced clade A dataset (panel A) comprises only strain HS and Columbicola spp. symbionts (with terminal nodes labeled according to the numbers listed in Additional File 5). Trees in panels BE are derived from the output generated by simulation with evolutionary rates (substitutions/site/cycle) of 0.002 (progenitor) and 0.016 (descendants) for panel B and E , 0.016 for both the progenitor and descendants for panel C and 0.016 (progenitor) and 0.128 (descendants) for panel D. Terminal nodes representing the progenitor sequence are labeled “prog” and descendants are labeled with the prefix “d”, followed by the cycle number of their birth in the 5000 cycle simulation. The tree in panel E was obtained from a dataset in which one descendant was permitted to speciate at cycle 2500, giving rise to “cospec1” and “cospec2”. Mean bootstrap values (MBV), depicted at the foot of each tree were computed from bootstrap values obtained for all internal nodes in each tree. Only individual bootstrap values > 50% are depicted in the figure.
