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.

Detailed explanation-2: -To be considered analogous, the structures between the two species have to have the same function but they do not necessarily have the same anatomical features. Because analogous structures differ in anatomy as well as developmental origin they do not implicate a common ancestral origin.

Detailed explanation-3: -Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous but not homologous.
