Bright plumage in birds is favored because:
It attracts mates reflects key principle in quiz on sexual selection + pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, It attracts mates 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 It attracts mates fits helps integrate natural selection,
