Detailed explanation-1: -Analogous organs are those organs that have some superficial resemblance, perform similar functions and yet, have different evolutionary origins and hence, different anatomical structures. Homologous organs are organs which have similar functions but different origins.

Detailed explanation-2: -Analogous structures have different morphology, which means they are different in structure but have similar function. Let’s take our bat wing again, and this time compare it to a butterfly wing and a bird wing. The bone structure of the bat wing is closer to the bone structure of a human arm than it is to a bird wing.

Detailed explanation-3: -Analogous structures are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature (compare to homologous structures) and which evolved in response to a similar environmental challenge.

Detailed explanation-4: -(P) Those organs which have the same internal structure but different functions, are called homologous organs. (Q) Organs which have different basic design but have similar appearance and carry out similar functions are called analogous organs.
