Explanation:

Analogous structures are body parts with similar functions but different evolutionary origins, which form via convergent evolution (unrelated species evolving similar traits due to similar environments). Bat wings (modified forelimbs) and insect wings (outgrowths of exoskeleton) share flight function but no common winged ancestor, fitting this definition. Homologous structures share origins, vestigial structures are reduced/non-functional, and divergent evolution leads to different traits from a common ancestor, which do not apply here.

Answer:

analogous; convergent
