Which of the following is an example of a homologous organ?Group of answer choicesRetina of an octopus, retina of a manLeg of a dog, leg of a spiderWing of a bat, wing of a birdSpines of a sea urchin, spines of a hedgehog
Solution 1
The correct answer is "Wing of a bat, wing of a bird".
Homologous organs are organs that have the same basic structure and developmental origin, even though they may serve different functions in different species. The wing of a bat and the wing of a bird are both used for flight, but they have different structures and functions. The bat's wing is a modified mammalian forelimb, while the bird's wing is a modified reptilian forelimb. Despite their different functions, they have a common ancestral origin, which makes them homologous organs.
