Practice question
Question
Which group lacks common ancestor?
Explanation
Polyphyletic reflects key principle in quiz on cladogram+pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Polyphyletic aligns with experimental and theoretical evidence from population genetics, behavioral ecology and molecular phylogeny. Textbooks like Campbell Biology, Futuyma Evolution and Hartl Principles illustrate supporting data. Understanding why Polyphyletic fits helps integrate natural selection, environment.
