The recognition of long-branch attraction implies that there is some other evidence that suggests that the phylogeny is incorrect. For example, two different sources of data (i.e. molecular and morphological) or even different methods or partition schemes might support different placement for the long-branched groups. Hennig's Auxiliary Principle suggests that synapomorphies should be viewed as de facto evidence of grouping unless there
