Answer:
A monophyletic group must include all species that are descended from a common ancestor, and cannot include any species that are not descended from that common ancestor. Modern evolutionary classification uses a method called cladistic analysis to determine how clades are related to one another. Evolutionary taxonomy, evolutionary systematics or Darwinian classification is a branch of biological classification that seeks to classify organisms using a combination of phylogenetic relationship (shared descent), progenitor-descendant relationship (serial descent), and degree of evolutionary change.
Explanation:
The goal of phylogenetic systematics, or evolutionary classification, is to group species into larger categories that reflect lines of evolutionary descent, rather than overall similarities and differences.
