Final answer:
Cladistic methods of phylogenetics identify monophyletic groups based on shared derived traits.
Step-by-step explanation:
Cladistic methods of phylogenetics use techniques that identify monophyletic groups based on shared derived traits. Clades, or monophyletic groups, consist of an ancestor and all of its descendants. These methods compare traits in related species to determine their evolutionary relationships and construct cladograms to visually represent these relationships.
