Question
Which of the following is an example of homologous organs?
- Bat wing and bird wing
- Bat wing and cat limb
- The limbs of a cat and limbs of a tortoise
- None of the above
Hint:
Homologous structures have the same evolutionary origin and different functions.
The correct answer is: Bat wing and cat limb
Bird and bat wings are analogous as wings, but as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings, but they did inherit forelimbs from a common ancestor with forelimbs.
Hence, it is an example of homologous organs.
