- If a taxonomist constructs a rooted phylogenetic tree for a group of living species, the structure of the tree alone can be used to distinguish hypotheses of monophyly versus nonmonophyly of a particular subgroup. If monophyly is rejected for a particular subgroup, tree topology alone cannot distinguish paraphyly from polyphyly. What additional information is needed to distinguish paraphyly from polyphyly?arrow_forwardBranch, clade and monophyletic group are perfectly synonymous. Select one: True or Falsearrow_forwardFor each combination of species, indicate whether the group they form would be monophyletic, paraphyletic, or polyphyletic.
