Final answer:
Butterflies, bats, and birds possess analogous structures for their wings, which evolved independently but share a common vertebrate ancestor.
Explanation:
Analogous structures best describe the wings of butterflies, bats, and birds. These structures have similar functions but evolved independently in response to similar environments, providing evidence for natural selection. Despite being analogous, the wings' bones are homologous, indicating a common vertebrate ancestor.
