Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Both butterflies and bats have the ability to fly due to wing development. How would you describe the evolutionary relationship of the animal’s wings?
A
polytomy
B
homoplasies
C
analogous
D
vestigial
Explanation: 

Detailed explanation-1: -But in both cases, the wings are used for flying. These animals would have to adapt to the same ecological niche as other organisms. Hence, they may have evolved similar organs. So, the correct answer is “analogous ‘’.

Detailed explanation-2: -Butterfly possesses wings with fold of membranes associated with muscles and no bones. But the wings of bat are supported by their bones. They have same function which is flying. Such organs which have different origin but same function are called analogous organs.

Detailed explanation-3: -No, wing of bat and wings of butterfly should not be considered as homologous organs because they have different structure and origin but have the same function of flying so they are analogous organs.

Detailed explanation-4: -Insect wings lack bones, but bird and bat wings have them. Butterfly wings are covered in scales, bird wings in feathers, and bat wings with bare skin. All of these organisms have adapted to life in the air and in doing so have evolved wings.

Detailed explanation-5: -The wing of a butterfly and the wing of a bat are analogous structures. Both can fly with their wings but their origins are not the same. The wings of bats are composed of bones whereas the wings of butterflies are not composed of bone and have a specifically different structure.
