Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The wing of a bat and a humans’ arm have different functions and appear very different. Yet, the underlying anatomy is basically the same. therefore, these structures are examples of
A
geographic isolation
B
analogous structures
C
homology
D
reproductive isolation
Explanation: 

Detailed explanation-1: -So, the correct answer is Divergent evolution.

Detailed explanation-2: -Homologous Structures Example A great example of homologous structures are the wings of a bat and the arms of a human. Bats and humans are both mammals, so they share a common ancestry. Both a bat’s wing and a human’s arm share a similar internal bone structure, even though they look very different externally.

Detailed explanation-3: -Features of animals that have similar structure are classified as homologous if they have a common evolutionary origin, even if they have different functions in different animals. A classic example of homologous structures is that of the wing of a bat and the arm of a human.

Detailed explanation-4: -Answer and Explanation: The wing of a bird and the arm of a human are examples of c. homologous structures. This is because they are structures which have a similar evolutionary origin despite the fact that they play different roles.

Detailed explanation-5: -The wing of a bird is a modified forelimb. It is adapted for an aerial mode of living i.e. used for flying. Whereas, the forelimb in humans is called an arm. It is used for various purposes like holding, clutching, lifting, writing, etc.
