What are organs called that evolved from a common ancestor but perform different functions?
Answer and explanation
Correct answer: Homologous organs
The governing concept is homology. Homologous organs have a similar underlying structural plan because they were inherited from a common ancestor, although their functions may differ after adaptation to different environments. For example, the forelimbs of humans, whales, and bats share a basic skeletal pattern but serve different purposes. Option A is therefore correct. Analogous organs share function but not basic origin, while vestigial organs are reduced remnants.
