The wings of a bird and the wings of an insect are:
Open in App
Solution
The correct option is D analogous structures and represent convergent evolution
The process of evolution in which two species, not related to each other by common ancestry, develop similar characteristics due to similarity in their habitats is known as convergent evolution.
Analogous organs are a product of convergent evolution. Analogous organs have different basic structures and origin but have evolved in such a way so as to perform the similar function. The wings of a bird and the wings of an insect are analogous structures and represent convergent evolution. Both serve the same function, but each evolved independently.
On the contrary, homologous organs are those organs which have a common ancestral origin. These are similar in basic structures but perform different functions. Forelimbs in mammals provide a good example of homologous structures. In these animals, the same structure (forelimb) developed along different directions due to their adaptations to different needs because of varied habitats. This type of evolution is called divergent evolution. Hence, homologous organs are the products of divergent evolution.
So, the correct answer is option C.
