1. HOMOLOGOUS ( morphological and anatomical evidences ) .These are the organs that have same basic structural plan and origin but different functions.
2. ANALOGOUS
These are the organs that have different origin and structure plan but same function
They Are Analogous
because yea
They don't. Homologous structures provide evidence for evolution not analogous structures.
Homologous Structures
Similar structures that have evolved independently are called homologous structures. An example would be the wings of a bird and the wings of an insect.
Analogous!
They Are Analogous
analogous
They are both. They are homologous because they are both examples of a vertebrate forelimb. They are analogous because they were adapted for flight independently of one another.
Analogous Features.
Homologous organs have similar looking structure and similar origin but different functions . Whereas analogous is just the opposite analogous organs are those that have similar function but different origin and structure
Structures

Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
In biology, homologous structures are defined as structures which serve the same purposes because they evolved from the same source (divergent evolution), the opposite of analogous structures, which serve the same purpose but evolved through convergent evolution. Birds' wings and bats' wings are both homologous and analogous. As wings, the two are analogous, but as forelimbs, the two are homologous.
The human arm would be homologous, as it is homologous to various other animals, such as a whale's fin, or a chimpanzee's arm.
