A chain handhold added in 1964 and extended in 1976 makes the hour-long climb easier, but it is still a steep, hike to the top, where
Long branch attraction a wider, fast evolving group, those branches may be misinterpreted as closely related. As such, "long branch attraction" can in some ways be better expressed as "branch length attraction". However, it is typically long branches that exhibit attraction. 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
