The wings of a bird and front limbs of a reptile or mammal are which of the following?

Question

Quizplus · Accepted Answer

The wings of a bird and the front limbs of a reptile or mammal are homologous structures because they have the same basic structure, indicating a shared evolutionary ancestry. However, they may have different functions (e.g. flight vs. walking) and may have evolved adaptations to suit those functions. Analogous structures are structures that have the same function but different structure and do not indicate a shared ancestry, while vestigial structures are non-functional remnants of ancestral structures. Embryonic structures refer to structures present during development but may disappear or transform in the adult organism. Artificial structures are man-made and not relevant to biological evolution.
