Detailed explanation-1: -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-2: -Homologous organs are organs that have a similar structure but perform different functions in different animals. Although the anatomical structure of the organ is similar the function differs. The wings of birds, hands of humans, and wings of bats are examples of homologous organs.

Detailed explanation-3: -Homologous structures homologous-structures Homologous structures are anatomical structures in organisms that share the same basic form. For example, the bones in the appendages of humans, dogs, birds, and whales all share the same overall construction resulting from their origin in the appendages of a common ancestor.

Detailed explanation-4: -An example of homologous structures are the limbs of humans, cats, whales, and bats. Regardless of whether it is an arm, leg, flipper or wing, these structures are built upon the same bone structure. Homologies are the result of divergent evolution.

Detailed explanation-5: -They have the same set of bones i.e. humerus, radius, ulna, and phalanges. This is because genetically, both these structures originate from the same structure of the last common ancestor.
