Explanation
cretaceous reflects key principle in quiz on geological time scale+pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, cretaceous 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 cretaceous fits helps integrate natural selection, environment.
