- A Organs that share the same evolutionary origin but differ noticeably in their function and form
- B Organs with different evolutionary origin but same function (e.g., wings of birds and insects)
- C Organs found mainly within the vertebrate animal lineage specifically, rarely elsewhere
- D Vestigial organs retained largely unchanged from a distant common ancestor over time
Correct answer: B. Organs with different evolutionary origin but same function (e.g., wings of birds and insects)
Explanation: Analogous organs have the same function but different evolutionary origin and basic structure. They show convergent evolution. Example: wings of birds (modified forelimb bones) and wings of insects (outgrowths of thorax) - both for flying but structurally different.
Concept context
