What are analogous structures?

Back

Analogous structures are body parts in different species that perform similar functions but do not share a common evolutionary origin.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that may not perform the same function but consist of similar kinds of structures, indicating a common ancestry.
