Final answer:
Phylogenetic classification attempts to replicate evolutionary relationships among species but acknowledges its limitations. Classification based on shared characteristics may not always reflect evolutionary relationships accurately. For example, a hippopotamus may be the closest living relative of a whale.
Step-by-step explanation:
Phylogenetic classification attempts to replicate the evolutionary relationships among species but acknowledges that there are times when it may be better not to do so. This is because phylogenetic trees are hypotheses and are modified as new data becomes available. Additionally, classification based on shared characteristics does not always reflect evolutionary relationships accurately. For example, a hippopotamus may be the closest living relative of a whale, despite resembling a pig more closely than a whale.
