In his view, it was only possible to determine the best approximation of phylogenetic trees, rather than demonstrate any of them conclusively.

In Phylogeny A, there are 4 total changes that resulted in 4 different species. In Phylogenies B and C, there are still 4 total species represented, however, they take 6 and 8 changes, respectively, to create them. http://dunnlab.org/phylogenetic_biology/phylogenies.html
