In sexual selection, which trait in peacocks is often cited as advantageous for mating?

• A. Large ornate tail
• B. Camouflage coloring
• C. Short beak
• D. Strong legs

Answer: (C)

Sexual selection explains why certain traits evolve because they help individuals attract mates, even if they make survival a bit harder. In peacocks, the standout is the male’s large, ornate tail (the train) with eye-like patterns. This tail is showcased in elaborate courtship displays, and females preferentially choose mates with more impressive trains. The attraction isn’t about camouflage or hiding from predators; it’s about signaling genetic quality and vigor to potential mates. Although a huge tail can hinder movement or increase risk, the mating advantage it provides drives selection for that trait. The other options don’t serve as effective mating signals in peacocks—camouflage aids survival, while a short beak or strong legs aren’t the primary displays used to attract mates.
