1 Answer

Answer :

Analogous organs are those organs which I have different basic structural design and developmental origin but have similar appearance and perform similar functions. Example: The wings of birds and bats look similar but have different design in their structure. They have a common function of flying but their origins are not common. So, birds and bats are not closely related.
