A scientist has developed 3 different phylogenies that describe the relationships between different species of elephants. 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.
