Group selection is considered:
Controversial reflects key principle in quiz on altrusim & hamilton rule+pyqs, where evolutionary mechanisms shape genetic variation and adaptation.

Textbooks like Campbell Biology, Futuyma Evolution and Hartl Principles illustrate supporting data. Understanding why Controversial fits helps integrate natural selection, environment.
