Explanation
24 h reflects key principle in quiz on behavior pyqs solved-section f, where evolutionary mechanisms shape genetic variation and adaptation. In this context, 24 h 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 24 h fits helps integrate natural selection, environment.
