The genus Bassiana, as well as the three species within it, formed monophyletic units (support of 100, 100 and 1.0 for MP, ML, and BA analyses except for Bassiana platynota where BA analyses provided only poorly support for its monophyly; Fig. 2).
Although FastTree 2 is not quite as accurate as methods that use maximum-likelihood SPRs, most of the splits that disagree are poorly supported, and for large alignments, FastTree 2 is 100 1,000 times faster.
Indeed it has long been suspected that fast evolutionary rates and compositional biases can lead to misleading phylogenetic signal and poorly supported splits for deeper relationships.
This was felt to be particularly important in those organisations where the RO was poorly supported and for ROs who were not thought to meet the expected standard.
Nintendo's long delay in releasing a competing 3D console and the damage done to Sega's reputation by poorly supported add-ons for the Genesis (particularly the Sega 32X) allowed Sony to establish a foothold in the market.
Conversely, Nintendo's long delay in releasing a 3D console and damage caused to Sega's reputation by poorly supported add-ons for the Genesis are considered major factors allowing Sony to gain a foothold in the market.
When difficult nodes are encountered, the next logical step is to add taxa and/or data under the reasonable assumption that additional taxa or characters might enable resolution and/or provide support for poorly supported nodes.
These results suggest that removal of misleading signal in phylogenomic datasets can result not only in increased resolution for poorly supported nodes, but may serve as a tool for identifying erroneous yet highly supported topologies.
In fact, we are strongly disinclined to even propose informal names for poorly supported groups that happen to occur in our highest likelihood tree unless subsequent research provides more support for them.
A constraint tree for 63 nonparasitic taxa was constructed using the MP topology of the "B series" tree from Soltis et al. [ 1] with relationships for poorly supported clades left unresolved.
