Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which best describes the similar function of wings in birds and butterflies?
A
embryological structures
B
homologous structures
C
analogous structures
D
vestigial structures
Explanation: 

Detailed explanation-1: -Analogous organs are defined as the organs of different animals having different structures but perform the same functions. An example of analogy includes the wings of a butterfly or insects and birds that are not looking anatomically similar but perform similar functions.

Detailed explanation-2: -Answer and Explanation: The wing of a bird and a butterfly wing are analogous structures, whereby the organisms do not share a common ancestral history. Birds and butterflies adapted to their changing environments and converged for a common function-flight-the only similar evolutionary process observed in both species.

Detailed explanation-3: -Analogies are similar characteristics shared by two different organisms because of convergent evolution. For example, the wing of a dove and the wing of a butterfly are analogous; the bird lineage and the insect lineage evolved wings independently of one another.

Detailed explanation-4: -The wings of a bird and of an insect are analogous organs. Both of these species have wings that they use for flight and yet their wings came from dissimilar ancestral origins.

Detailed explanation-5: –Wings of Pigeon and wings of butterfly or housefly, or wings of bat and wings of butterfly or housefly are the examples of analogous organs that are opposite of homologous organs.
