Question

What is meant by analogous organs? Taking a suitable example, explain how they support the theory of Organic Evolution.​

Answer 1

Answer:

Analogous, organs have different developmental origin and structural design but perform similar function,e.g. the wings of birds and insects are analogous organs indicating that they have different, ancestors but have a convergent evolution. In this way, analogous organ supports the theory of organic evolution.

Analogous organs-

Analogous organs are defined as the structures that differ in their basic structures or developmental origin but appear similar or perform similar functions. The most common example is the wings of bat and wings of bird. They perform similar functions .i.e. help the organism to fly, but there structure is different. Bat wings are made up of flaps of skin which is stretched between the bones of the fingers and the arm while the wings of bird are made up of feathers extending all along the arm.

Presence of analogous structures supports the process of convergent evolution, where unrelated organisms develop similar characteristics to adapt to similar environments.
