homologus organ
Homology in Animals. Organs such as bat's wing, wings of birds, seal's flipper, forelimb of a horse, and human arm have a common underlying anatomy that was present in their last common ancestors; therefore their forelimbs arehomologous organs.
analogus
Analogous organs are the opposite of homologous organs, which have similar functions but different origins. An example of an analogous trait would be the wings of insects, bats and birds that evolved independently in each lineage separately after diverging from an ancestor without wings
vestigial
vestigial organ n. A rudimentary structure in humans corresponding to a functional structure or organ in ancestral animals.

Vestigial Organs
The organs which are present in reduced form and are functionless in one group of organism but in developed form and in active state in other group of organism are called vestigial organ.
Homologous Organ
The organ which are similar in origin and structures but different in functions are called homologous organ
Analogous Organ
The organ which are similar in function but different in origin and structure are called analogous organ
