Comparison between analogous and homologous structures

Analogous Structures	Homologous Structures
These are similar structures or traits in different species that have the same function but different evolutionary origins.	These are structures or traits that share a common evolutionary origin, although they may serve different functions.
They do not share a common evolutionary ancestor and do not indicate a close evolutionary relationship between species.	They share a common evolutionary ancestor and indicate a close evolutionary relationship between species.
They are structurally similar on the surface due to functional similarities but have different internal structures.	They can be structurally similar both externally and internally due to shared ancestry.
These structures result from convergent evolution, where unrelated species independently develop similar structures.	These structures result from divergent evolution, where a common ancestor gives rise to species with different traits.
Example: both bat wings and bee wings are used for flight.	Example: The human arm and bat wing have similar limb bones but different functions.
