Why are homologous organs considered evidence of evolution even when their functions differ?
Answer and explanation
Correct answer: Because their basic structure points toward common ancestry
Homologous organs have a similar underlying structural plan because they were inherited from a common ancestor, although adaptation may give them different functions in different organisms. For example, the forelimbs of humans, whales, and bats have corresponding bones but serve different purposes. Therefore option A is correct. Colour and identical function are not required, and homologous organs are not limited to plants.
