Body parts of different species that have the same function but different structure and origin
Analogous structure
Body parts of different species that have the same function but different structure and origin. Analogous structure. Analogous structures are features in different species that have similar functions but are not inherited from a common ancestor.

The process by which unrelated species develop similar traits in similar environments
Convergent evolution
The process by which unrelated species develop similar traits in similar environments. convergent evolution. In simple terms, convergent evolution is when different animals end up looking or acting alike because they live in similar places or deal with similar problems.

A similar structure in different species, like a whale fin, bat wing and your arm
Homologous structure
A similar structure in different species, like a whale fin, bat wing, and your arm. Homologous structure. Homologous structures are body parts in different species that look similar because they evolved from a common ancestor.
