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: -For example, analogous structures are structures that are similar or resembling in certain respects, e.g. in function or in appearance but not in evolutionary origin or developmental origins, such as the wings of a butterfly and the wings of a hummingbird are analogous.

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: -Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example of homologous structures are the limbs of humans, cats, whales, and bats.

Detailed explanation-5: -Analogous structures are similar structures in unrelated organisms. These structures are similar because they do the same job, not because they share common ancestry. For example, dolphins and sharks both have fins, even though they aren’t related. Both species developed fins because of how (and where) they live.
