Question

question: which of the following is/are an example of a homologous structure? answer options: select one of four fish fin wisdom teeth vermiform appendix eyeballs

Explanation:

Homologous structures are those that have a similar evolutionary origin (share a common ancestor) but may have different functions. Fish fins, when compared to limbs of tetrapods (like human arms, bird wings), share a common skeletal structure origin (from the same embryonic developmental pathways in related species). Wisdom teeth and vermiform appendix are vestigial structures (reduced function), and eyeballs in different species can be analogous or homologous but among the options, fish fin is a classic example of a homologous structure (e.g., fish fin and human arm have homologous skeletal elements in their evolutionary lineage).

Answer:

Fish fin
