- Why would it be nice to have classification reflect phylogeny accurately that is, to only name monophyletic groupsarrow_forwardin our system of classification, organism R and X are placed in the same group. Organism B is placed in a different group. This tells you: R and X are less closely related to each other than to B B and R are more closely related to each other than to X X and B are more closely related to each other than to R R and X are more closely related to each other than to B none of these organisms are relatedarrow_forwardWhich of the following statements is correct about the hierarchy of the taxonomic system currently used to classify organisms?
