With your knowledge of convergence, choose a reason why wings are present in far-related species. Explain.

  • Wings evolved from arms used to capture small prey.

  • Wings evolved because bipedal animals were leaping into the air; large wings assisted leaping.

  • Wings evolved from gliding ancestors who began to flap their gliding structures in order to produce thrust.

  • Wings were created by an intelligent designer.
